COMETIC Top End Gasket Kit - 99 mm - Yamaha C3279-EST

A failing top-end gasket will cost you power and reliability—and on high-output 4-stroke engines running boost or chasing peak naturally aspirated performance, factory gaskets often can't handle the cylinder pressures. The COMETIC C3279-EST delivers the sealing integrity your engine demands with multi-layered steel construction and proprietary Viton rubber coating designed to eliminate hot spots and prevent gasket failure under extreme conditions. This kit includes everything needed for a complete top-end R&R, so you're not hunting down individual seals when you're already torn down.
