Product Details

This is a Mahle OE Piston Ring set, specifically the THM-13 model. These rings are designed for engine rebuilds where precise sealing between the piston and cylinder wall is critical for performance and longevity. They feature a 3.551 inch bore size with a 1.5mm thickness, suitable for many engine applications that require a standard, well-built ring set.

Mahle is a well-known name in engine components, and this set reflects their commitment to reliable parts. The Napier hook design on the oil ring helps to scrape oil from the cylinder walls more effectively, which can improve oil control and reduce oil consumption. This is a plain ring set, meaning it doesn't have specialized coatings, making it a straightforward and dependable choice for many common engine builds.

When rebuilding an engine, ensuring proper ring seal is paramount. These rings are made to fit right and perform as expected, helping to restore compression and maintain oil integrity within the combustion chamber. Always refer to your vehicle's specific service manual for detailed installation procedures and torque specifications.
