Mahle Rings 4.605in Bore 1/16in 3/16in PC479 Fire Power High Tension Perf Eng Set Moly Ring Set

This is a Mahle OE Moly Ring Set designed for performance engines with a 4.605-inch bore. It features high-tension rings, specifically a 1/16-inch top ring and a 3/16-inch oil ring, often referred to as the PC479 Fire Power set. These rings are crucial for proper engine sealing, ensuring optimal compression and efficient oil control.

Mahle is known for well-built engine components, and this ring set is no exception. The moly coating on the top ring helps reduce friction and wear, which is especially important in higher-performance applications where engines are subjected to more stress. The high-tension design ensures a solid seal against the cylinder wall, helping to maintain consistent power output and prevent blow-by.

When rebuilding or refreshing a performance engine, a quality ring set like this Mahle offering is essential for achieving reliable power and longevity. Ensure your cylinder walls are properly honed to match the ring type for best results.
