One of the biggest problems that tuners face is that once they install aftermarket modifications to their wheels, of course you lose out because your warranty is as good as toilet paper. Well, BMW has something that could settle that right up if you have a 335i/xDrive.

Being introduced as the M Performance Power Kit, it gives your 2012 and later 3'er a bump of 20 hp and a 32 and 17 lb.-ft. increase in torque for automatic and manual vehicles, respectively. Not bad, but certainly a bit stingy considering the package starts at $1,100 (plus installation).

Keep in mind this only includes software or replacement ECU, an air intake, an engine cover and some stickers.

BMW's press release follows:

BMW M Performance Power Kit Now Available for 2012 and Later BMW 335i Sedan.

Increased power, responsiveness, and sensation are hallmarks of BMW’s fully-developed kit.

Woodcliff Lake, NJ – BMW today announced a new M Performance Power Kit for the 2012 model year and later BMW 335i Sedan and 335i xDrive Sedan models. The M Performance Power Kit joins the existing M Performance Parts line which includes chassis, aerodynamics, exhaust system components, and trim accessories. Developed through consultation by the engineers at BMW M GmbH, the M Performance Power Kit is immediately available through all Authorized BMW Centers in the US, with MSRP starting at $1,100 (plus Installation) and retains BMW’s 4-Year / 50,000-mile New Vehicle Warranty when purchased with a new vehicle.

More Power. More Dynamic. More Emotion.
Once the Power Kit is installed, the vehicle’s rated horsepower is increased from 300 to 320 on all models. Automatic transmission-equipped models enjoy a 32 lb-ft peak torque increase (to 332 lb-ft), while manual transmission-equipped models benefit from a 17 lb-ft peak torque increase (to 317 lb-ft). All models receive a re-mapped accelerator pedal calibration for more dynamic throttle response, and the Power Kit produces a signature, highly-emotional “exhaust burble” sound during engine overrun conditions. 0-60mph acceleration is improved 0.2 seconds compared to standard 335i models, while 50-75mph times drop by a full half-second.

The BMW M Performance Power Kit features comprehensive engine tuning via advanced software 335i and 335i xDrive Sedan models. The kit includes updated software or replacement engine DME (electronic control unit), high-capacity engine air intake system, signature BMW M Performance engine cover, and rocker panel decals. This gives the 335i Sedan or 335i xDrive Sedan a substantial power boost (+20 horsepower) while retaining the original 50-state legal emissions certification and fuel efficiency ratings.

Installed with Confidence.
The vehicle’s original BMW New Vehicle Limited Warranty is not affected by the installation of the M Performance Power Kit, and Kit components are covered under warranty for the duration of the original BMW New Vehicle Limited Warranty (4 Years / 50,000 miles) if purchased at the time of new vehicle sale, or for 2 Years / unlimited miles if installed later. is ranked #1 on Google for auto show photos!
