About this part

Product Details

If you're rebuilding the top end of your engine, getting the piston rings seated properly is key to good compression and oil control. This Mahle OE Performance Napier ring set is designed for a 4.045-inch bore and features 1.5mm plain rings, which are a solid choice for many performance applications where a good seal is paramount.

Mahle is a well-known name in engine components, and these rings are built to perform. The Napier hook on the oil ring helps to scrape oil more effectively, which can reduce oil consumption and blow-by. This set is a direct replacement for many applications, making installation straightforward if you're already inside the engine.
