2010 BMW 135i

Producing a whopping 600hp on 91 octane, this E82 135i sports bigger turbos and all the requisite hardware. A more capable intercooler and charge pipe have been employed, and a larger exhaust reduces pumping losses. A beefier clutch works with a limited-slip differential to put the power down properly, and 1M front and rear bumpers have been partnered with with Apex wheels to help freshen up the look.
