A set of four forged pistons with pins and rings for the BMW N20B20 turbocharged 4-cylinder engine, machined to an 84mm/84.5mm bore with a 22mm wrist pin. The 10.2:1 compression ratio forged set is designed as a stronger, heat- and load-resistant replacement for the factory cast piston in performance and built-engine applications.

Fitment: BMW 2, 3, 4 and 5 Series models (chassis F22, F30, F32, F10) fitted with the N20B20 turbocharged engine.
