MAHLE 42248CP.020 Engine Piston Ring Set Oversize - 020

The MAHLE 42248CP.020 is an engine piston ring set engineered to OE specifications, offering a precision-fit solution for engine rebuilding and overhaul applications. Manufactured to the same standards as original equipment components, this ring set delivers reliable sealing performance, reduced friction, and minimized oil consumption.

Key Features:

• OE-Level Engineering: Designed to meet or exceed original equipment manufacturer specifications for a direct-fit replacement
• Friction Reduction: Advanced ring geometry and surface treatments minimize friction losses for improved engine efficiency and fuel economy
• Reduced Ring Mass: Lightweight construction lowers inertia forces on the piston assembly, supporting higher RPM capability and reduced wear
• Minimized Oil Consumption: Precision-engineered oil control ring design limits oil passage into the combustion chamber
• Extended Service Life: Premium materials and coatings resist wear, scuffing, and thermal fatigue for long-lasting performance
• .020 Oversize: Sized for cylinders bored or honed to .020 inch over standard diameter, making this ideal for engine rebuilds requiring standard overbore work

MAHLE is a globally recognized OE supplier to major automotive manufacturers, bringing that same level of engineering expertise to the aftermarket. The 42248CP.020 piston ring set is an ideal choice for engine builders and professional technicians performing complete engine rebuilds or cylinder freshen-ups requiring .020 oversize components.
