BMW has let loose a new M Performance Power Kit for its F30-generation 335i and 335i xDrive sedans. Starting at $1,100 for the kit – installation is extra – your car will be fitted with a new ECU and air intake on the functional side and an M Performance engine cover and rocker panel stickers on the decorative side. The Power Kit raises the 3.0-liter inline six-cylinder's horsepower rating from 300 to 320, and on automatic models, torque gets a boost from 300 pound-feet to 332 lb-ft – manual transmission models get a smaller bump to 317 lb-ft.

According to the Bavarian automaker, you'll be able to hear the change in the overrun exhaust note, and 0-60 mile-per-hour times drop by 0.2 seconds. The package is available now at all BMW Centers in the US, and if you get it installed when you purchase the car new, it will get the same four-year, 50,000-mile warranty as the vehicle. Have it done after the fact and the kit will be warranted for two years and unlimited miles. There's a press release below with some more details.

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.

      I wouldn't risk voiding warranty on a BMW if it's still active... but 20 HP for $1100 is a good upgrade stock-for-stock

        You can bet that 20hp figure is underrated.

      Pretty much similar performance figures for the 335is and z4is engines. A nice deal at $1100 dollars, less than what you would pay for an aftermarket exhaust system.

      Bravo BMW. I never understood why other German automakers like VW wouldn't offer a factory upgrades like this. They would rather flag your car for a tune and void the warranty.

      What about the 328i? Get it up to ~260HP and ~275 lb. ft. of torque. That would be nice. Cheaper, lighter, less-thirsty, and a lot of fun.

      White must not be a good color for this car. It looks like it has been in an accident or something.

      The best thing BZmW could do is put the car on a diet!

      Since BMW under-rate their engines from factory by about 20-30 hp and torque anyways...maybe this doesnt actually change anything??? LOL

        BMW does not under rate their engines. Nobody under rates their engines. The IIHS ensures that nobody under rates their engines.

          The IIHS is a private organization that is concerned with vehicle safety in crashes, they have nothing to do with engine ratings. Companies under rate engines all the time. The most egregious under rating is probably the (Neon) SRT-4 which produced more power at the wheels than was rated at the crank. Not sure if BMW is at that level, but the fact that they always out accelerate every car of similar power. ALWAYS means that there's something up besides gearing differences.

          Your leaving out important facts. Who funds the IIHS and the fact that they use the crash and dyno test results to help set insurance rates for vehicles.

      I'd rather call Burger Tuning and get a Juice Box for far less money. My best friend had a 335i with a JB3 and their intakes. Their customer service is second to none, the owner even responds to emails on holidays. Truly amazing customer service.

        Enjoy taking that off, 30 minute job, anytime you need to go in for warranty. JB4 is better of course, but this is a viable option for those with warranties that don't want to worry about removing it before taking it in for service.

      OOORRRR, you can get a Cobb tune for $800 and get +80 hp/ +100 tq.

        Have you ever bothered to call Cobb? They do not recommend their tune over 85 degrees or below 32 degrees.
