JE Pistons forged piston kit for the BMW S50B32: a set of six 87.0mm bore pistons with a 10.10cc dome yielding an 11.50:1 compression ratio. Built for high-demand European and racing applications, the kit replaces factory pistons with a race-capable, engine-specific solution for rebuilds and performance builds. Forged in the USA from 2618 aluminum, the design uses JE’s Forged Side Relief forging, an accumulator groove to reduce ring flutter, and skirt coating to lower friction. Includes premium wrist pins, locks and JE Pro Seal rings for a complete install.
