** SPECIALLY MADE PISTONS - FOR USE WITH RB25DET/RB26DETT CYLINDER HEADS**
FEATURES:
Ultra Flat Ring Grooves - essential in achieving and maintaining the best seal possible.
CNC Machined Pin Bores - ensures perfectly matched and aligned pin bores every time.
Slipper Skirt Forging - Mahle Motorsport's technology for strong, light-weight and low drag forgings.
Grafal® Coating - Mahle Motorsports' Grafal® anti-friction skirt coating is like no other on the market. It is graphite impregnated to reduce drag like many other skirt coatings, but this is where the similarities end. The screen print application provides superior adhesion and is designed to last 100,000+ miles. Because Grafal® is a compressible membrane with a unique cushioning property, harsh contact between the piston skirt and the bore is dramatically reduced. Resulting in much less wear on the bore and significantly reduces piston skirt fatigue.
