Description
Subaru EJ25 04-08 STI Super Alloy Exhaust Valves by Ferrea
Ferrea super alloy valves represent the highest level of sophistication in valve technology. We proudly introduced the next generation of extreme heat resistant valves, specifically developed to withstand the brutal punishment of NHRA Top Fuel and Funny Car applications. We have developed a specially processed high nickel-based alloy, and a unique heat-treatment process, which yields extreme heat resistance and enormous tensile strength properties, (far beyond conventional Inconel materials).
Ferrea Super Alloy valves are designed for use on the exhaust side only.
