Ferrea Copper Bronze Intake & Exhaust Valve Guides Set STD 4G63T Eclipse Talon DSM 1G 2G Evo 1-9

Valve Guides are a wear-item. They wear over time and eventually should be replaced. The higher you rev, and the harder you push your engine, the more important tolerances become. If you are spending the time and money to upgrade your valvetrain, be sure your tolerances are correct by replacing your high mileage guides with brand new aftermarket valve guides.

Our high quality copper-bronze blended alloy valve guide is developed with proprietary heat treatment processes allowing for greater heat dissipation, heat resistance, and lubricity properties for the next generation of high performance race engines.
