BMW has released a new performance upgrade kit for the 2012 335i and 335i xDrive sedans. The dealer-installed package adds a big dollop of performance to the sports sedans, yet comes with the peace-of-mind of a factory warranty.
The M Performance Power Kit includes a new air intake, a new engine cover, new doorsill plates, and a reprogrammed computer for the turbocharged 3.0-liter inline-six engine. On cars with a six-speed manual transmission, power climbs from 300 hp and 300 lb-ft of torque to 320 hp and 317 lb-ft. BMW 335i sedans with an eight-speed automatic see power rise to 320 hp and 332 lb-ft.
BMW claims that installing the M Performance Power Kit cuts 0.2 second from a 335i sedan's 0-to-60-mph time, so figure on a 5.2-second sprint for rear-wheel-drive models. The extra torque means that passing performance from 50 to 70 mph improves by 0.5 second. Moreover, BMW says the new programming results in "more dynamic" throttle response.
The upgrade package costs $1100, plus the cost of dealer installation. If it is ordered with a new car, the M Performance Power Kit is covered under the same warranty period as the car, four years/50,000 miles. Drivers who add the kit to a car later still get two years/unlimited miles of cover.
Despite the gain in performance, BMW says cars with the Power Kit still meet emissions requirements in all 50 states, and that fuel-economy ratings are unaffected. Coupled with the warranty coverage and relatively modest cost, the M Performance Power Kit sounds like a good deal for BMW 335i drivers who want even better performance.
Other performance parts in the BMW catalog include a stainless-steel exhaust for the 335i, as well as a big-brake kits, and unique wheels.
