Mahle Rings 4.535in Bore .043in 1/16in 3/16in PC479 Fire Power High Tension Perf Eng Moly Ring Set

This Mahle PC479 Fire Power ring set includes the piston rings you need for a high-tension performance engine build. Designed for a 4.535-inch bore, these rings feature a .043-inch top ring, a 1/16-inch second ring, and a 3/16-inch oil ring. The moly coating on the top ring helps reduce friction and improve durability, making them a solid choice for performance applications where engine stress is higher.

Mahle has a long history of supplying well-built engine components, and this ring set is no exception. The high-tension design ensures a strong seal against the cylinder wall, which is crucial for maintaining compression and preventing blow-by in performance engines. This helps to optimize power output and keep your engine running efficiently under demanding conditions. Proper installation is key to getting the most out of these rings; always refer to your engine's service manual for specific ring gap and installation procedures.
