Ferrea Racing 6000 Series Competition Engine Exhaust Valves Subaru EJ20

The Ferrea 6000 Series Competition Valves are designed to provide excellent reliability in an environment of high spring pressures and roller cams, at a budget price. They have higher fatigue resistance and tensile strengths than their competitor’s best offerings.

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