Product Details
This is a Mahle OE THM-13 piston ring set, designed for a 3.917 inch bore. These rings are a key part of your engine's sealing system, working with the piston to maintain compression and control oil flow within the cylinder. Proper ring function is essential for engine performance and longevity.
