Mahle Rings Performance Steel Napier 2nd Ring 4.320in x .043 .135in RW 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 Steel Napier 2nd Ring set is designed to help ensure a good seal between the piston and cylinder wall, which is key for both power and keeping oil where it belongs.

The Napier hook design on the second ring helps scrape oil off the cylinder wall as the piston moves down, preventing it from getting into the combustion chamber. This helps reduce oil consumption and keeps your spark plugs cleaner. The steel construction offers good durability for this critical sealing component.

This set is intended for specific engine builds where precise ring sizing and function are important. Always refer to your engine's service manual for correct installation procedures and specifications.
