Wiseco KE242M95 Forged Piston Set BMW S38B36 3.6L 95mm 12.0:1 CR Professional Series

The Wiseco KE242M95 is a Professional Series forged piston set engineered for the BMW S38B36 3.6L 24-valve inline-six engine. Designed for serious engine builders and racers, these no-compromise pistons deliver the strength, precision, and durability required for high-compression and forced-induction race builds.

Each piston is forged and machined in the USA from 2618 aluminum alloy, offering superior tensile strength and thermal resistance compared to cast alternatives. The dedicated forgings are shaped specifically to the final piston geometry, resulting in a lighter yet stronger component that exceeds industry standards. Wiseco's advanced heat-treating and finishing processes further ensure consistent performance and long-term reliability.
