Sealed Power Engine Piston Ring Set P/N:E-991K
Sealed Power E-551KC piston ring set for the 1994-1995 Mazda MX-3 4-cylinder 1.6L and other vehicles seals each piston against its cylinder wall. Each Sealed Power piston ring in the set meets or exceeds OEM specifications.
Oil burning, blue-gray exhaust smoke or low compression can mean worn rings, which is when an engine piston ring set goes in during a rebuild. Worn valve stem seals or a clogged PCV system can also be behind oil use, and a leaking head gasket can lower compression, so find out which applies before buying rings.
The 1994-1995 Mazda MX-3 4-cylinder 1.6L, the 1986-1994 Mazda 323 4-cylinder 1.6L and the 1991-1994 Mercury Capri 4-cylinder 1.6L all take this ring set, one set per engine, and so do other vehicles. Open the "Vehicles it fits" section to check your exact model and engine.
