What is the benefit of plasma-moly inlay on these rings?

The plasma-moly inlay on the top ring face is a hard coating that helps reduce friction and wear against the cylinder wall. This contributes to better engine longevity and consistent performance, especially in demanding applications.

What does the 'Napier hook' refer to on the top ring?

A Napier hook is a specific shape on the back of the top ring, designed to improve oil drainage and reduce the risk of oil scraping past the ring. It's a design feature aimed at enhancing oil control.

Can these rings be shipped to California?

Product Details

These Mahle OE performance piston rings feature a plasma-moly inlay on the top ring, a tough material that holds up well under high heat and friction. This set is built for a 3.435-inch bore, and each top ring measures 1.0mm thick with a 0.143-inch Napier hook. You get a bulk quantity of 48 rings, making this a solid choice for engine builders working on multiple projects or high-volume shops.

Mahle is a well-known name in engine components, and these rings are designed to meet the demands of performance applications. The plasma-moly coating is applied to the face of the ring, which is the part that directly contacts the cylinder wall. This coating helps reduce friction and wear, contributing to better engine longevity and consistent performance over time. The steel construction offers good strength and durability, essential for keeping a tight seal between the piston and cylinder wall under pressure.

When rebuilding an engine, getting the piston rings right is crucial for proper compression and oil control. This set is intended for use in performance-oriented builds where reliability and durability are key. Remember that these rings are not CARB approved and cannot be shipped to California.
