2012 BMW 135i

This E82 135i was optioned with the desirable M-Sport package and features a few key upgrades to give it some extra grip and more go. An upgraded intake and intercooler provide easier access to the air the motor craves and reduce charge temperatures, while a more efficient exhaust mitigates pumping losses. An ECU tune ties it all together to unlock more grunt, and a beefier clutch puts the added power down reliably.
