Mahle Rings Performance Plasma Steel Top Ring 4.295in x 1.0MM .143in RW HVOF Moly Ring Set

This set includes Mahle OE Performance Plasma Steel Top Rings, specifically sized at 4.295 inches with a 1.0MM width and a .143 inch RW HVOF Moly construction. These rings are designed to be a direct replacement for your engine's top piston ring position, crucial for sealing the combustion chamber and managing oil consumption.

The plasma-sprayed steel top ring offers improved durability and wear resistance compared to cast iron alternatives, especially under demanding conditions. The HVOF (High Velocity Oxygen Fuel) Moly coating on the ring face further enhances its ability to reduce friction and resist scuffing, contributing to a longer ring and cylinder life. This updated ring design aims to maintain optimal compression and oil control.

It's important to note that this ring set is not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific service manual for proper installation procedures and torque specifications.
