Developed for the serious speed enthusiast and professional racers alike, PowerPak pistons are all dual coated with a Phosphate coating that provides the piston’s characteristic gray appearance. This dry lubricant provides a lubricant film protection in the pin bores and ring grooves. Each slipper skirt is also treated with Grafal, MAHLE’s proprietary coating to reduce wear, drag, scuffing, friction and piston noise.
