Description

A compromised head gasket is the fastest way to lose compression, leak coolant, and watch your GSXR's performance tank. The COMETIC C8663 is engineered to seal reliably across the extreme thermal cycles and combustion pressures your sportbike generates, whether you're running stock boost or pushing forced induction. This is the gasket choice when you need zero margin for error.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
