BMW recently announced that they would be offering a performance power kit upgrade available for the 135i and 335i. We just caught a glimpse of the first install on one of our cars!
The performance power kit is a software tune that gives the 335 an extra 20HP. The full factory warranty is still maintained and the exhaust note picks up a slight "burble" under accerlation.
Let us know your thoughts! Will you be installing the power kit on your car?
