What is the purpose of the plasma-moly coating on the oil ring?

The plasma-moly coating on the oil ring is designed to reduce friction and wear. This helps to extend the service life of both the piston rings and the cylinder walls, ensuring consistent performance over time.

Why is a low-tension oil ring important?

A low-tension oil ring helps to reduce internal friction within the engine. This can lead to improved fuel efficiency and a slight increase in power output by minimizing parasitic drag.

Can these rings be shipped to California?

No, these piston rings are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

These Mahle piston rings feature a ductile iron oil ring with a plasma-moly coating, measuring 1.5mm for the top ring, 3.0mm for the second ring, and a low-tension oil ring designed for a 4.035-inch bore. This specific combination is chosen to ensure a good seal and efficient oil control within the cylinder, which is critical for engine performance and longevity. The plasma-moly coating on the oil ring helps reduce friction and wear, contributing to a longer service life for both the rings and the cylinder walls.

Mahle OE rings are well-built for reliable performance. The low-tension design of the oil ring is particularly important for modern engine builds where reduced internal friction is a goal, helping to improve fuel efficiency and power output. This set is designed to fit precisely into the piston grooves, ensuring proper tension and sealing against the cylinder wall when the piston is in motion. Proper installation is key to achieving the intended performance benefits and durability.
