Mahle Rings Performance Napier THM-13 4.105 x 1.0MM 136in RW Plain Ring Set (48 Qty Bulk Pack)

When you're rebuilding an engine, getting the right piston rings is crucial for sealing the combustion chamber and ensuring proper performance. This set from Mahle OE features a Napier hook design on the second ring, which helps to improve oil control and reduce blow-by, especially in high-performance applications. The 4.105-inch bore size and 1.0mm thickness are common dimensions for many popular engine builds.

Mahle OE is known for making well-built engine components, and these rings are no exception. The Napier hook on the second ring is a notable design feature that helps scrape oil off the cylinder wall more effectively than a standard ring, contributing to better lubrication and reduced wear. This bulk pack of 48 sets means you'll have plenty on hand for multiple engine builds or for a shop environment.
