Forged piston set machined to an 82.00mm bore with a 10.2:1 compression ratio, built from high-strength 4032-grade aluminum alloy (enriched with copper, nickel, and magnesium) for low thermal expansion and strong wear resistance under sustained high-boost operation. CNC-finished for tight ring-land tolerances and balanced reliability in turbocharged performance builds.

Fitment: BMW 3 Series/4 Series/M3/M4/X3/X4 and Toyota GR Supra, B48/B58 engine (B58B30).
