Phenolic Fuel Rail Spacers – WARR Performance 60-0001

This is a 4 piece phenolic spacer kit that replaces the aluminum spacers used to attach fuel rails to the Holley Hi Ram and similar intake/ fuel rail kits. These will help insulate the rails from the intake which minimizes heat transfer to your fuel rails and fuel. This helps your fuel pump(s) run cooler, which can lead to longer pump life and fewer vapor lock issues.
