Mahle Rings Performance Steel Napier 2nd Ring 3.576in x 1.0MM .136in RW Plain Ring Set

This Mahle OE piston ring set features a 1.0MM thick steel Napier hook design for the second ring. This specific design helps to scrape excess oil off the cylinder wall as the piston moves, which is crucial for preventing oil from entering the combustion chamber and causing issues like blue smoke or fouled spark plugs. The Napier hook shape is a well-known design for its effectiveness in oil control, especially in performance applications where engines are pushed harder.

Mahle is a well-known name in engine components, and this set is built to meet the demands of performance engines. The steel construction of the second ring offers good durability and resistance to heat. When you're rebuilding an engine or looking to improve its oil management, a well-made piston ring set like this is a critical piece of the puzzle. Proper installation is key to ensuring these rings seal effectively and perform as intended.
