Mahle Motorsport Performance Pistons-The Mahle Diesel PowerPak is a complete race-proven piston assembly kit composed of hand deburred, forged, performance coated pistons, high-quality steel pins, round wire locks and low drag performance rings.

For additional performance, Mahle applies its proprietary Grafal anti-friction coating to each piston skirt.
