    Ferrea 6000 Series +1mm Competition Valves (Mitsubishi Evo X 4B11T) - Modern Automotive Performance

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