MAHLE Motorsports Performance Cast Pistons .040 ,16.8CR No Pockets (2001-2016)*

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.
It may seem crazy, but you really can get 8, 14, or even 22 more HP with Mahle pistons and rings. The secret is in Mahle's ultra flat ring grooves and low drag rings. Improved sealing minimizes parasitic drag to create ''free'' horsepower.

Performance coatings include a phosphate dry lubricant (not to be confused with a thermal film coating) that is used to protect against ring micro-welding and pin galling during initial startup and break-in. For additional performance, Mahle applies its proprietary Grafal anti-friction coating to each piston skirt.

All new MAHLE Group products sold and marketed by MAHLE Aftermarket Inc. and their affiliates are warranted to be free from defects in original materials and workmanship for a period of one (1) year from the date of purchase.
