Description

The CP-20 oil rings from Mahle Original consists of a barrel-faced top compression ring for better seal and quicker break-in, and reverse torsional twist second ring for better oil control. The CP-20 oil rings have a 20-degree ear angle to ensure side seal around the ring and are chemically polished for better oil drain-back, but most importantly they can withstand the harsh operating environments in today's engines. Ease of installation makes the Mahle Original CP-20 oil rings the premier choice for rebuilders everywhere. For piston rings and accessories that deliver more horsepower and torque, the Mahle Original performance line proves time and again that it should be the piston ring of choice under every hood—regardless of the application.
