Mahle Rings Performance CP20 Oil Ring Assembly 3.922in x 2.0MM Std Tension Plain Ring Set

When you're rebuilding the top end of your engine, getting the piston rings right is crucial for sealing and performance. This Mahle OE CP20 oil ring assembly is a standard tension set designed for a 3.922-inch bore, with a 2.0mm oil ring width. Mahle is a well-known name in engine components, and these rings are built to meet the demands of a fresh engine build.

This set includes the oil control rings needed to properly scrape oil from the cylinder walls, which helps prevent oil from entering the combustion chamber. Proper oil control is key to preventing excessive smoke, oil consumption, and premature wear on other engine parts. The standard tension design ensures a good seal against the cylinder wall without being overly aggressive, making it a solid option for many rebuild applications.
