Current or future owners of the BMW 135i or 335i can benefit from performance packages from BMW Performance available either as a retro-fit to an existing car, or port fitted to a new car before delivery.

Two power kits are available, with both taking horsepower to 320hp, offering a 20hp increase over stock for the factory turbo engines. Likewise, torque is increased to 332 lb-ft when the car is equipped with an automatic transmission, or 317 lb-ft if you have a manual or DCT transmission.

Once installed, the new software is claimed to improve acceleration to 60mph by 0.2sec faster than the standard 335i. It’s also reported to reduce the 50-70mph run by 0.5sec.

The software was specially developed by BMW’s own engineers for the 135i and 335i, allowing the cars to maintain the original emission certification, fuel efficiency and it won’t affect the vehicle’s original BMW Limited Warranty. Potential owners should note that Power Kits should only be installed on 135i and 335i vehicles equipped with option code S840 (increased top-speed limiter, which includes an additional oil cooler).

To coincide with the announcement, BMW is offering an introductory price on all Power Kits until the end of 2011. This means the Version 1 Power Kit engine software for all 135i, 335i and X6 produced up to 4/2010 is $599 MSRP.

Version 2, which uses the same software but adds an auxiliary water cooler and an enhanced radiator fan to reduce the thermal stresses on the engine during extreme driving, will cost $1199 MSRP. These prices don’t include installation. Contact your local BMW dealer for full pricing.
