The CorkSport Advantage

Injector Seals

Whether you are running stock power or seeking high HP numbers your fuel injectors are working under extreme conditions. Both 1800+ psi fuel and combustion gases are fighting to escape around the seals between the injector and the head.

If you’ve seen the OEM seal, you know it’s a no brainer why they struggle to handle the pressure. Get rid of them already and upgrade to the CorkSport Injector Seals. Check out the individual product listing linked above for more details!

Each injector o-ring kit includes four full sets of the four components that make up the seal between your injector and fuel rail.
