F83 BMW M4 with Injen Intake for BMW S55 & Evolution Racewerks S55 Chargepipes + Painted Engine Cover

Yesterday we had the pleasure of giving this bright yellow F83 BMW M4 Cabrio a major increase in performance here at ModAuto. Sr Mod Expert Alan Wei helped coordinate the power package to give this M4 some major oomph, and many of the mods we did here were on our Best Mods for BMW M4 guide a while back.

The Injen intake for BMW M4 alone is good for an increase of +12whp and 23wtq, not to mention the significant change in the engine note of that sweet turbo six S55. Compounding that increase is the fact that this M4 rolled in already equipped with the ESS E-tronic tuner for S55 BMW M4 (and M3 as well), boosting output to 550HP / 560TQ – before factoring in the Injen Intake.


This shade of yellow really is impactful on the M4. It’s one of those polarizing “love it or hate it” kind of things, but it’s really grown on us.

To go with its blacked out look, we removed the OEM exhaust tips and had them ceramic coated black to better match the car.

F83_BMW_M4_Evolution_Racewerks_Chargepipes_Injen_Intake-20 The bright polished tubes you see there are a set of Evolution Racewerks Chargepipes for BMW M4 – at higher boost levels, already the stock chargepipes are beginning to fail, so replacing them with these chargepipes from Evolution Racewerks is both a boon to performance and a great preventive item that eliminates a potential point of failure.F83_BMW_M4_Evolution_Racewerks_Chargepipes_Injen_Intake-21 All together, the chargepipes, intake, painted engine cover and ESS e-Tronic tune (again, which was already installed on the vehicle when it came in) should put down quite a bit of power when the car is dyno’d later today at another local shop. We reckon the car will be well into the 5’s at the wheels, even on a conservative dyno.F83_BMW_M4_Evolution_Racewerks_Chargepipes_Injen_Intake-22

With its blacked out coordinated details, this M4 Cabrio looks incredible from the side profile, and that stance happens to be factory, as BMW Cabrios always are lower from the factory than the hardtop.
