MAHLE Motorsport pistons are manufactured using precision forging and machining processes, with close attention paid to ring groove quality, tolerances, and consistency. Each piston in the PowerPak program includes multiple surface treatment applications for added protection and long-term performance durability. The lightweight forged construction reduces reciprocating mass while maintaining the structural integrity demanded by high-output engines.

Backed by over 95 years of motorsport heritage, MAHLE Motorsport supplies professional race teams at every level of competition. The PowerPak program makes that same race-proven technology accessible for performance street builds, sportsman class racing, and professional race engines alike.
