Mahle Rings Performance Napier Steel 2nd Ring 4.085in x 1.0MM .136in RW Plain Ring Set

Mahle OE is known for making reliable engine parts, and these performance Napier steel second rings are a solid option when you're rebuilding or refreshing an engine. These rings are designed to help your pistons seal properly against the cylinder walls, which is key for good compression and efficient combustion. The Napier hook design on the second ring helps to scrape oil down the cylinder wall, preventing it from getting into the combustion chamber and causing issues like smoking or oil burning.

This set features a 1.0mm thickness for the second ring, which is a common size for many performance applications. The steel construction offers good durability, and the plain finish means it's ready to go to work without any special coatings to worry about. When you're putting an engine back together, getting the piston ring setup right is critical for its long-term health and performance.
