Mahle Rings Performance Plasma Steel Top Ring 4.105in x 1.0MM .143in RW HVOF Moly Ring Set

Mahle is well-known for making solid OE replacement parts, and this performance plasma steel top ring set is no exception. If you're rebuilding an engine and need reliable piston rings, this set is designed to help your engine run smoothly and efficiently. These rings are made with plasma-coated steel, a strong material that holds up well under the heat and pressure inside your cylinders.

The top ring features a 1.0mm thickness and a .143 inch face width, with an HVOF Moly coating. This specific design helps create a good seal between the piston and cylinder wall, which is crucial for proper compression and preventing oil from getting into the combustion chamber. This means you can expect improved engine performance and potentially better fuel economy compared to worn-out rings.
