A set of six forged pistons with pins and rings built for the BMW N55B30 single-turbo inline-6 engine, sized at 84mm/84.5mm bore with a 22mm wrist pin. The set carries a 10.2:1 compression ratio and a Moly-coated skirt to reduce piston-to-bore friction, giving the engine a stronger bottom end for higher-boost or built-engine applications versus the OEM cast piston.

Fitment: BMW 1, 2, 3, 4 and 5 Series models (chassis F20, F22, F30, F32, F10) fitted with the N55B30 turbocharged engine.
