Ferrea Exhaust Valve Guides Set of 8 STD 4G63T all years Mitsubishi Eclipse Evo 1-9 VIII IX

Ferrea Valve Guides are stronger than stock and help pull heat off of the valve, increasing its longevity. They are precision machined from high quality Manganese Bronze material. They are ideal for both intake and exhaust applications and are compatible with both stainless steel and titanium valves.
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.
