SET OF EIGHT

Ferrea Competition Plus Standard Intake Valves for the Evo represent the highest level of sophistication in valve technology. We proudly offer their next generation of extreme heat resistant valves, specifically developed to withstand extremely brutal punishment. These valves set the standard for all Turbocharged, Supercharged, Nitrous Oxide, and compression restricted race motors.

For the Sport Compact Cars, Ferrea has introduced its New Super Alloy Import-Tuner Valve program. These valves are specifically designed for use in racing engines that are subjected to extreme exhaust temperatures. No other valve on the market has been designed with the Tribological consideration as their Super Alloy Valves have for these specific applications. Once again Ferrea is setting the pace.

Details of this specific part are as follows:

To manufacture the valves, Ferrea use our exclusive two-step slow forging process using EV8 stainless steel on both intake and exhaust valves. They provide a special heat-treatment and stress relieving process, along with hard chrome stems and friction-welded hard tips. Then they finish with a swirl polished head. The valves feature flow improvements to deliver the power needed for today's sophisticated racing engines.
