To be fair the M Performance Power Kit comes with more than just some software. You also get a new intake, plastic engine cover, and decals to let the world know how much faster and cooler your 335i now is.
A 20 horse increase at the crank on this motor is VERY mild. Cobb and BMS are getting much more power out of it in the aftermarket than 20 crank horses for less money so any enthusiast reading BimmerBoost will simply dismiss this "Power Kit" from BMW. Unless they really, really need those decals.
This is aimed at people at the dealer buying the car who don't know any better and want to preserve their factory warranty with a small bump in power. Basically, not people reading this site or those interested in max performance.
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 – March 26, 2013… 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.
