2008 Infiniti G37 S on Forgestar F14 Gunmetal 19×9.5 ET22  19×11 ET37 on Tanabe Sustec Pro Coilovers 

Picking up where the Z 2+2 left off and correcting the little things that could be improved upon from the outgoing V35 chassis Infiniti G35, the heavily revised V36 Infiniti G37 offers sportscar fun in a grand touring coupe package.

While it’s better than it’s ever been with the best iteration the VQ37VHR V6 engine, unfortunately, the G is nowhere near as good looking or as exciting as it should be the way it rolls off the factory floor- a few choice mods are necessary. Left as is, the G37’s stock exterior is about as attractive as a piece of soggy toast.

With that said, in this article we’ll be looking at some of the mods out there for the G37 to transform your stock G37 into the car it’s supposed to be. Just a few fairly basic changes can have a huge impact on the performance, look and sound of your Infiniti. Written in terms everyone can understand, we’ll be recapping the 4 Best Mods for Infiniti G37 on the market today that can turn your G from bland to bananas with just a few simple parts.

1 Wheels

When it comes to the single easiest way to enhance the look and performance of your car with a single part, there’s nothing like a set of wheels for your Infiniti G37 to dress it up. Wheels take up a huge chunk of your car’s visual real estate, so a great looking set of wheels can be a massive change. The factory wheels on the G37 are kind of depressing and about as interesting as beige wallpaper, so the right set of wheels can turn your G into a real stunner.

Check out how aggressive this G37 coupe looks lowered with KW Coilovers on a set of Forgestar CF5V Wheels for Infiniti. The concavity and the wide split 5-spoke face’s curves compliment the G37’s flowing lines beautifully, while the ARK Performance Exhaust peeking out from underneath creates a more menacing look.

Here’s a look at the side profile of the CF5V‘s on the same G37 to give you a better idea of the design. Forgestar Wheels, as the name might suggest, are rotary-forged, or flow-forged, a manufacturing process for wheels that produces a wheel that’s lighter and stronger than a similar wheel produced by casting.

Forgestar F14 Wheels are another handsome option that goes amazingly well with the G37, and can be had in that wonderfully aggro super deep concave profile that is so popular these days. The G37S above is lowered on a set of Tanabe Coilovers to eliminate the wheelgap and bring the ride height down and rolling on a set of 19×9.5 DC / 19×11 SDC Forgestar F14 Wheels for Infiniti in Gunmetal Finish, it looks positively incredible. The F14 pairs really well with cars fitted with the S or IPL G ground effects or with other exterior modifications.


2008 Infiniti G37 S on Forgestar F14 Gunmetal 19×9.5 ET22  19×11 ET37 on Tanabe Sustec Pro Coilovers 

The combination of the F14’s with the G37S exterior, complimented by a Tanabe Medallion Touring Exhaust, gives this particular G a kind of JDM-meets-Euro feel that’s both aggressive and classy all at once.

If you’re into more of a stanced aesthetic, there’s Forgestar fitments available for you as well, because Forgestar manufactures every set of wheels to order – taking into account things like whether your specific car is lowered, slammed to hell static, bagged, equipped with a big brake kit or widebody and so on.


Forgestar F14 in Matte Candy Red

In addition to being available in a huge variety of diameters and concavity, Forgestar wheels can also be ordered in a broad spectrum of colors.

Forgestar CF5 in Gunmetal

If a 5-spoke look is more your thing, consider the Forgestar CF5 as an option. The bold lines of the clean 5-spoke design go well on nearly any build and the gloss gunmetal finish pairs beautifully with the car’s natural silver.

VMR V710 19in Gunmetal Wheels

Maybe something with more of a euro flair is your thing – our friends from VMR Wheels also have some great options for G37 fitments. VMR’s classic Gunmetal VMR V710 wheels for Infiniti look great on Sedans, creating a look more akin to something German rather than Japanese.

Infiniti_G37_Sedan_VMR_V710_Gunmetal_19in (13)The V710 is also available in matte black and hyper silver finishes – coordinating your wheel color to compliment or contrast your paint will help your G look its best.

The great thing about the wheels for Infiniti G37 on the market right now is that there’s tons of diversity in styles and looks, allowing you to find something that’s uniquely your style, and our Mod Experts are always happy to suggest options that suit your style and your budget (Chat live at or call 714-582-3330). Avant Garde Wheels is another stellar wheel option for the G37, offering dozens of styles, ranging from the Avant Garde M590 above with its handsome clean mesh design…


…to the Avant Garde M580 with its organic look to its broad, concave 5-spoke design. These offer a great accent to the dynamic curves of the G’s body, whether coupe or sedan, both have the same flowing curves and pair well with similarly fluid wheels.

on 245/40-19 275/40-19 Hankook Ventus Tires on Tanabe NF210 Springs for G37s

If you’re after a more sports oriented look, a set of TSW Nurburgring Wheels for Infiniti are a great fit and pair well with the bodystyle of both coupe and sedan. The harder lines of the Nurburgring in Matte Gunmetal help create a more aggressive dynamic.

The side profile on these is fantastic, as you can see. It’s worth saying that tires are an important piece of the puzzle- after all, your wheels are only as good as the thing that connects yo to the road.
TSW Nurburgring Wheels Infiniti/Nissan/Genesis

By the way, as we mentioned, TSW Nurburgring Wheels in Matte Gunmetal look great on the sedan too.

Whatever your taste, there’s a wheel that’s right for you that will bring out the beauty in your G’s organic, flowing curves. As one of the simplest ways to make a huge difference in the look and performance of your car, there’s really no excuse not to dump those stock wheels.

After getting rid of the stock wheels like one eradicates bubonic plague, the next glaring issue keeping your G37 from looking great is the rather glaring, big-foot 4-wheel-drive-ass wheel gap that’s standard on these cars. The ridiculous wheelgap makes your G look bloated and robs it of its otherwise sleek look. That’s why lowering your G37 Suspension should be tight on your list right after a set of wheels.Russ_Infiniti_G37_Vert_IMg001

One of the easiest way to drop your G37 is with a set of lowering springs, and one of the most trusted brands for lowering springs is Eibach. That’s why Eibach Pro-Kit Springs for Infiniti G37 are so popular with our G37 customers.


Balancing a drop in ride height with comfort, Eibach Pro-Kit Springs are a great “goldilocks” option that handles better than stock without sacrificing much ride comfort, and are available to fit every flavor the G37 comes in, Sedan, Cabrio, Coupe, RWD and AWD alike.

Feel like you need a JDM spring for your JDM luxury grand tourer? Tanabe NF210 Springs for Infiniti G37 are a fantastic option for you.

Offering a 1.0in drop up front and a 1.3 in drop at the rear, Tanabe NF210 Springs for Infiniti G37 are reputedly the most comfortable lowering spring on the market. Balancing comfort while still offering much improved handling performance and eliminating the nasty stock wheelgap so that your G37 actually looks like a sportscar rather than bloated.

To give you a better idea of what we mean, check out this before/after contrasting a stock Athens Blue G37 Coupe against the Athens Blue G37 Coupe from the previous photo, which has been lowered with a set of Tanabe Springs and fitted with a set of TSW Nurburgring wheels. The difference in appearance is amazing. It’s like the difference between a set of Mom Jeans and Yoga Pants.

But then there’s still the problem of the fact that the factory shocks are still there, and if your G has more than 50k on it, your stock tires are donezo anyway and due for replacement, and throwing a lowering spring onto a set of blown out factory shocks won’t result in a good ride or handling. On top of that, if you factor in the cost of replacing the shock absorbers when you do the springs, a set of coilovers is actually a surprisingly economical option.

Since coilovers replace both the shock and the spring together, as a paired unit, coilovers perform better and often ride better than factory shocks with lowering springs. Contrary to popular belief, coilovers aren’t just for the hardcore trackday enthusiast, but they’re also great for daily drivers that want to have control over their ride height exactly, or who just want to go lower than springs allow and even for the superior handling. Coilovers are available in models ranging from pre-set coilovers where there’s nothing but ride height to adjust – a painless option for those who don’t want to mess with a ton of settings – to fully adjustable race-oriented models that allow you to adjust the bound, rebound and can include camber caster plates.

One of the coilover options available for G37 Suspension are the Tanabe Sustec Pro Coilovers for Infiniti G37, which solidly eliminates the nasty excessive wheelgap, and sharpens the handling performance of the G even further with sport tuned valving and a lower center of gravity. Not to mention, the stance looks amazing with a great set of wheels.


On the other hand, let’s say you want something that offers a lot of adjustments, but you want a good value for the money- in that case, a set of BC Racing BR Coilovers for Infiniti G37 could be the thing for you.

Offering 30-way adjustability at a pricepoint of just 10-benjamins as of press time, BC Racing Coilovers are available for the G37 Sedan and Coupe, and for both the G37x and RWD.



If you live in a snowbelt state and want to get low, a set of KW Coilovers for Infiniti G37 are a great option, offering a corrosion-resistant stainless steel shock body and the quality components KW is known for.

Infiniti_G37_Ark_Exh_KW_V3_Forgestar_CF5V_GM-1 Check out the hardware. While KW does come at something of a premium, you do get a lot of extras like the little toolkit you see at the top of the photo.
Infiniti_G37_Ark_Exh_KW_V3_Forgestar_CF5V_GM-4You can see how the KWs fit into the front suspension of your G. The purple threaded perches are how you raise and lower the ride height of your car, and the knobs at the top are where you’d normally find the adjustments.
Infiniti_G37_Ark_Exh_KW_V3_Forgestar_CF5V_GM-7 In the rear, as with most coilover setups, is an adjustable perch rear spring.Infiniti_G37_Ark_Exh_KW_V3_Forgestar_CF5V_GM-22

Check out that stance on the KW Coilovers. Even though we’re only dropping the car a little more than an inch, that  change in ride height makes a world of difference.

Infiniti_G37_Rohana_RC7_MatteGraphite_20x10_20x11_img003Rohana RC7 Matte Graphite 20×10 / 20×11* AGGRESSIVE FITMENT NOT RECOMMENDED

Should you want to go even lower than you see the coilovers, you’ll want air suspension, like this Infiniti G37 on a set of Rohana RC7s in Matte Graphite. For air suspension, we offer AirRex Air Suspension for Infiniti, which offers digital ride height control to give you on-the-fly ride height adjustability. To accomplish this sort of fitment takes a ton of compromise, like rolled fenders and so on, and even with air ride, it’s still not a good idea to go driving around dragging chassis, but if you’re really serious about your stance game and aren’t afraid to spend some coin, Air-Ride is a fantastic way to go.


However you choose to get low, lowering your G37 will make it look better by eradicating the excess wheelgap. With the wheelgap gone, your wheels look even better and the body lines of the car look that much sexier.

Sure, the factory exhaust lets you hear some of that signature VQ V6 hum, but as an Infiniti model more oriented towards grand touring than sports, it has a much quieter exhaust note than the Z by comparison, and both of them really dampen the sound of that fantastic VQ37VHR far too much. Uncork your G37 Exhaust to unleash an exhaust note with some authority that’ll make people take notice and enjoy more horsepower and torque at your command when you stomp the go-pedal.


ARK Performance GRIP Exhaust on G37 Sedan with Polished Finish Tips

If you love that famous Nissan VQ sound, the ARK Grip Exhaust for Infiniti G37 is an ideal way to do it, enhancing the sound and power of your G without taking away from the things about the car that make it an Infiniti.




The ARK Grip Exhaust for Infiniti G37 is a great choice for the daily driver who wants a bit more sound, as this system offers minimal drone while cruising around but ramps up the noise when you sink the pedal to the floor.


Have a listen to the system in this video.




The Heimholtz Resonator chambers featured in the GRIP Exhaust system helps bring drone down to an absolute minimum, an issue some other competing systems suffer from.


And as we said earlier, the larger exhaust tips also look great on the car – the Burnt finish tips give the system a more aggressive edge if you’re feeling flashy…


..but also manages a classy, refined look in the standard polished finish as seen on this sedan. The ARK System gives you that signature VQ warble, but in a low-drone, low-bass setup that’s distinct to this system.


Contrast that to the sound of the Stillen Exhaust for Infiniti G37 Coupe, which also gives you that VQ warble we love but in a deeper, more bass-heavy tone than the ARK System. Stillen has had a long relationship with Nissan/Infiniti, making them one of the Go-To favorite parts manufacturers for the Nissan/Infiniti aftermarket community.

The Stillen Exhaust for Infiniti G37 differs in configuration between coupe and sedan, but the sound is very similar and both systems look great on the car, and are a bit less obvious than other exhausts for a more subtle look. The system above is for a coupe, with the mufflers side by side, rather than parallel.

And like most exhaust systems for the G37, you’ll see a nice little bump in power across the entire revband, a gain of around 19whp and 15wtq, according to their stats, giving you the power you need to leave other G’s behind at the stoplights.

As we mentioned, the system for a sedan on the other hand has the mufflers in parallel, with polished tips protruding just slightly beyond the fender for an aggressive yet refined kind of look.


Say perhaps, you want to go JDM with your Infiniti’s exhaust system – well there are two great options from Greddy for the G – we’ll start with the daily-friendly system. This is the Greddy SP Elite Exhaust for Infiniti G37. The quieter and obviously more daily-friendly of the two, this system offers a pleasant exhaust note, a great look and that JDM name that scores you the cool points you want.

Infinity G37 Greddy SP Elite Modbargains rear

Significantly quieter than either the ARK Exhaust or the Stillen options, the Greddy SP Elite system is a great choice for the discerning daily driver, and that quiet tone comes from the factory-style setup of the single unit muffler with dual tips feeding out on either side.


On the other hand, if you still want that JDM brand name but a more aggressive sound and that classic ‘tuner’ kind of look, the Greddy Revolution RS Exhaust for Infiniti G37 might be right up your alley. From the photo above you can see the large twin muffler cans with burnt tips really give the car a much more tuner-y kind of feel, which some with a more discerning ear or preference for quiet might not enjoy. However, if you want to get the most power out of your exhaust, really turn up the volume on your VQ and give your G an injection of much needed aggression, this is just your ticket. Guaranteed to turn heads your way wherever you go, this is a system for those who want to be heard.

The Greddy Revolution RS Exhaust for G37 is available with polished or burnt finish tips. As you can see from the photo above, this is basically a straight through system with minimal resonators and mufflers to give you G an angry roar when provoked with a stomp of the throttle. This system delivers more power than the SP Elite, but that extra volume means that it’s a lot more to listen to day to day, so be sure to listen to sound clips when deciding on an exhaust.


Of course, the Revolution RS Exhaust for Infiniti G37 also features a large GREDDY logo etched into the oversized tips for those much needed cool points.


Of course, Greddy isn’t the only JDM player in town – check out the Tanabe Medallion Touring Exhaust for Infiniti G37 Coupe, offering a sound that makes your VQ more satisfying to listen to, enhances the look of your G’s rear end and also yields the power benefits of a freer flowing exhaust system.


As the name suggests, the Tanabe Medallion Touring Exhaust is designed so that you can enjoy the car on long drives (you know, touring), making it ideal for a daily driven car.


Offering a modest gain of 16whp and 18wtq (with optional midpipe and Y-pipe), the Tanabe Medallion Touring Exhaust for Infiniti G37 delivers both an enjoyable VQ warble and more power at your command, all in a fantastic looking exhaust system.

These are just a few of the exhaust options available for both Infiniti G37 Coupe and Sedan – check out our full selection of exhausts for Infiniti G37 here – and if you don’t see something you’re looking for listed, just ask – we can probably get it. Consult our team of Mod Experts- call us at 714-582-3330, chat live with the Experts at or just stop by the ModAuto showroom M-Sat 8a-5pm in La Habra, CA and talk to an expert in person.

After addressing the exhaust system, the next place to get more power and sound out of your G is the other half of airflow into the motor – your G37 Intake.

4 Intake

While on the original VQ35DE, there was a single throttle body, the revisions made to the motor as it evolved into the VQ37VHR included the addition of a second throttle body, sharpening response and creating a greater potential for power. The factory airboxes, however, are both restrictive and quiet, not to mention boring to look at. If you’re looking to get better response when you hit the throttle, a richer engine note under acceleration and more horsepower and torque to the wheels, a high flow Intake for Infiniti G37 may just be the next mod you need to cross off your list. Available in long and short tube configurations, there’s a great selection of options available.


Injen Cold Air Intake System for Infiniti G35/G37

Injen Infiniti G35 / G37 Intake Polished SP1997P

If you’re after the most power, a long-tube cold air intake is going to be the way to go, like the Injen SP Intake for Infiniti G37, which replaces the entirety of the intake system, airboxes and all, rerouting the intake inlets to a point low inside the bumper, drawing in a colder aircharge, which means more horsepower to the wheels.

Injen Cold Air Intake System for Infiniti G35/G37 Installed

Injen Infiniti G35 / G37 Intake Polished SP1997P

Available in Polished or Wrinkle Black finish, the Injen SP1997 Intake for Infiniti G37 will deliver more power and torque to the wheels than a short-ram setup.

However, this can be a problem in snow belt-states and places where it rains a lot, where you might experience higher water levels.



Injen Infiniti G35 / G37 Intake Polished SP1998P

Speaking of the short ram configuration type setup that keeps the intake inlets mounted up high, ideal for places where rain and snow are a problem – and the short intake path means razor sharp, fast throttle response, and the filter’s location under the hood means you’ll have a bit more engine noise than you would with a long-tube intake setup.

Injen Infiniti G35 / G37 Intake Polished SP1998P

The Injen SP1998P Short Ram Intake for Infiniti G37 looks great under the hood and retains much of the factory tubing to deliver more horsepower and torque and a deeper engine note under throttle while looking closer-to-stock, and the heat shields both keep hot air away from the inlets and also creates a higher performance look under the hood.

Injen is by no means your only option either- Stillen has two great options for G37 intakes. In the photo above, we have the Stillen Gen 3 Long Tube Cold Air Intake for Infiniti G37, seen here without the front bumper installed so that the filter inlets aren’t obscured. This system relocates the air filters to directly behind the Infiniti Cheesewheel in the grille, creating an almost ram-airlike effect, but the black plastic shield seen in the photo also keeps unwanted moisture from soaking the filters and getting into the intake.


Here’s a look at the intake with the bumper installed.

As we’ve said before, the Long Tube Intakes for the G37 yield more power, with the Stillen Gen III Intake for G37 delivering a 18whp / 6wtq gain, yielding significantly more horsepower but noteably not a big change in torque overall, though top end torque is definitely improved.

Stillen also offers a Short Ram Air Intake, the Stillen Gen II Short Ram Intake for Infiniti G37, which also keeps the filter inlets mounted up inside the engine bay away from any potential for moisture ingestion, but also features molded plastic heat shields that create a better seal to keep heat away from the filter inlets and a cleaner, more “refined” look under the hood for those discerning gentlemen.

The Short Ram Intake features high flow tubing from the mass air sensor to the throttle body, replacing more of the system than the Injen system, but the more conservative design and more closed-off heat shields mean this translates into a modest gain of 6whp and 5wtq.


Delivering a massive power gain of 18whp / 20wtq according to their dyno sheets, last but not least, we have the Takeda Retain Cold Air Intake for Infiniti G37, which significantly increases power, uncorks the intake sound of the VQ and sexes up your engine bay. Check it out in the video above.


Available in a short ram or long tube configuration as well, the Takeda Intake for Infiniti G37 gives you that JDM panache as well as outstanding power gains.

Upgrading the intake system of your G37 will make every press of the gas pedal that much more satisfying with a better engine note and more power to sink you into the seat as you hit the throttle.
