With the B7 Audi A4 and S4 now getting a bit older, the B7 platform is becoming a bit more popular as a mod-worthy platform. The B7 was the first generation A4 to carry the 2.0 TFSI motor, and that means there are a good number of performance options available too.
In the next few paragraphs, we’re going to go over the best mods for the Audi B7 A4.
Where to start? Why not begin with the easiest mod – a set of wheels for B7 Audi A4.
There are quite a few great wheel options out there for the B7 platform – HRE Flow Form FF01 Wheels for Audi are a great looking option that’s fresh to the market, and are some of the finest quality wheels on the market anywhere. HRE Performance Wheels hasn’t earned their reputation with hype, after all.
Another great flow-form option are Forgestar F14 Wheels for Audi, which are custom-made to order. Each custom made set of Forgestar Wheels is machined to your exact fitment and offset, and are available in three levels of concavity to suit the concave trends of today’s wheel scene.
A few favorites of our experts are offered by VMR Wheels. These VMR V718 Wheels for Audi B7 A4 / S4 look great with the bodylines of the B7 chassis. For a easy, no hassle fitment without rubbing at all, a fitment of 19×8.5 ET35 (with 245/35-19 tires)
Our Audi experts also love VMR V708 wheels for Audi A4 – one look and you can see why.
2. Suspension Is Everything
Coilovers, or “coil-over-shocks” replace the spring and shock absorber completely, moving the spring directly onto the exterior of the shock body. The spring mounts are threaded, so the ride height can be adjusted accordingly. A lot of people are mistakenly under the impression that coilovers are expensive. While that might’ve been true once, that’s not the case anymore. This B7 Audi A4 is sitting on a set of Solo-Werks Coilovers for B7 Audi A4, which will set you back just a bit over five benjamins for a complete set of four coilovers. Since the coilovers replace both the shock and the spring, by default, there’s more parts to replace the function of – which means that on its face, a coilover “appears” to be more expensive than just springs, if you factor in that a set of lowering springs will wear out the shocks much much faster, you’ll want to budget for a set of shock absorbers to go with the lowering springs.Solo-Werks Coilovers for B7 Audi A4/S4 are a fixed damping coilover, meaning you don’t have adjustments for the shock, but each set of Solo-Werks coilovers is assembled with shocks that have been spec’d out specifically for that platform – and from what our experts and customers who’ve bought them tell us, the quality is damn good as well. Like seriously impressively good.
Like their springs, a set of Vogtland Coilovers for B7 Audi A4/S4 is designed to preserve your ride quality as much as possible while also enhancing the handling performance of your Audi as well as the lowered look you want. Vogtlands tend to be on the more conservative side, but this is simply a matter of personal preference. Only marginally more expensive than the Solo-Werks option, a set of Vogtland Coilovers is also very affordable.
3. Power Up Performance with a CAI + Exhaust
Upgrading your B7 Audi A4 Exhaust will wake up the car’s performance as well as allow you to actually hear your engine. We offer a range of exhaust systems from AWE Tuning, Billy Boat, Remus Innovation and other fine manufacturers of Audi A4 Exhaust systems.
A cat back exhaust like the Billy Boat Catback Exhaust for B7 Audi A4 offers an improvement in sound and performance.
And as you can see, the exhaust also changes the look of the rear of the car quite a bit for the better.
A Cold Air Intake will also wake up the performance of your 2.0 TFSI – there are several options available – this the AEM Cold Air Intake for B7 Audi A4 2.0 TFSI, which replaces the OEM airbox and filter with a much freer flowing unit, since the OEM Audi airbox tends to be a bit restrictive as it’s designed with minimizing engine noise in mind. In addition to the extra power, response will feel sharper and you’ll be able to hear your turbo more clearly. Check out the range of B7 Audi A4 Intakes here.
As with any turbocharged car, your Audi 2.0 TFSI responds really well to a larger intercooler. An upgraded intercooler offers cooler charge temps, resulting in more consistent performance and the ability to run more aggressive air/fuel and timing, thereby creating much more power. Evolution Racewerks Dual Side Intercoolers for B7 Audi A4 2.0 TFSI cool the incoming air charge the same way as the S4 with an intercooler on either side of the radiator, but there’s also the Evolution Racewerks Front Mount Intercooler for B7 Audi A4 2.0 TFSI.
A great example of the single core style is the AWE Tuning Front Mount Intercooler for B7 Audi A4, which is another outstanding intercooler option.
The last performance item we want to mention…
Diverter Valve / Blow Off Valve
Since the OEM diverter valves have a tendency to fail, and fail OFTEN, a diverter valve isn’t just a great idea for the performance aspect, but also for reliability. The Forge Motorsport BOV/Diverter Valve for VW/Audi 2.0 TFSI engines is a favorite solution of our experts to solve the problem, ensuring your 2.0TFSI is holding boost like it should.

5. Stand Out With Exterior Mods
An RS style grille for B7 A4 is a great place to start and fits the A4 just as well as the S4
One of the mods you won’t notice unless it’s pointed out are painted front reflectors – available for most European cars, these clean up the look of the car quite a bit.If you want a sportier look, of course, it’s hard to go wrong with the old stand by classic of adding a spoiler, like the Carbon Fiber Trunk Spoiler for B7 Audi A4/S4 seen here.
