Supertech Valve Guides are precision-engineered from high-strength Manganese Bronze, offering outstanding wear resistance and heat management in high-performance Subaru FA20 engines. Designed for both intake and exhaust valves, these guides ensure tight clearances and consistent valve operation, whether you're daily driving or pushing the limits on track.

For extreme performance and high EGT setups, optional copper alloy exhaust guides are available, offering up to 3x greater thermal conductivity for improved heat dissipation — ideal for turbocharged and supercharged builds.
