Overview

Mahle pistons were designed as a completely finished drop-in forged piston assembly. Other than filling the included performance piston ring set, everything is done for you. Mahle has over 80 years of piston manufacturing making pistons from OEM to Formula 1 racing. Mahle uses only the best technology to make these pistons. Mahle pistons come standard with anti-friction skirt coating for reduced drag. Mahle pistons are forged from 2618 low expansion aluminum alloy for high strength for the reduced piston to wall clearance. Forced Pin Oiling is used for increased wrist pin lubrication. Pin bores are CNC precision-machined. .927" High-Quality Steel Wrist Pin (118g), Performance 1.0, 1.0, 2.0mm rings, and Race Proven Round Wire Locks are included.
