More power. That's cool.

Energy that will leave nobody cold. With its engine optimisation, the BMW Performance power kit for the BMW 135i and the BMW 335i elicits new, high-performance sportiness from the vehicle. Which means more torque, more kW and more acceleration. To enable the engine to deal with this increased heat development, the power kit has an advanced cooling system. This perfect interplay guarantees a long operating life with no compromise in performance.
