BMW has announced a new Power Kit package for select vehicles equipped with the automaker’s turbocharged 3.0L inline-six engine. The new kit builds on the automaker’s Performance Edition package, which was launched for 335i models earlier this year. Like the previous package, the latest Power Kit is available for the 335i, but its application has been expanded to also include all 135i models as well as X6 models produced up to April 2010. The Power Kit can be optioned on new BMW models or retrofitted to older cars. The Power Kit is offered in two forms – the more basic Version 1 Power Kit and the more performance-minded Version 2 Power Kit. The Version 1 Power Kit is essentially a reflash of the vehicle’s ECU, boosting power to 320 horsepower. Torque is also increased – growing to 332 lb-ft for automatic cars and 317 lb-ft for vehicles equipped with BMW’s manual or DCT transmission. That added power reduces 0-60 runs by 0.2 seconds and acceleration between 50-75mph by 0.5 seconds. The Version 2 Power Kit builds on the Version 1 package, adding an Auxiliary Water Cooler and an Enhanced Radiator Fan to reduce engine temperatures. The Version 1 Power Kit carries an MSRP of $599 while Version 2 rings the register for $1,199. Neither price includes installation and BMW warns that additional air ducts or other components may be required for Version 2. Both Power Kits are, however, covered by BMW’s factory warranty.
