This 2006 335i is a full-blown sleeper project: SpeedTech bottom-mount single turbo and VRSF race intercooler aim for serious power, while MHD and xHP flashes manage fueling and drivability. BBS-style alloys and Bilstein-based B12 springs dial in the stance, and the matte-black grill plus M-Tech bumper give a stealthy look — complete with a fake 320i badge for laughs. Mechanical bits like a serpentine guard, crank seal, and 3.5 bar TMAP make it robust. It’s a raw, intentional build that surprises at the strip and on the road.
