Ferrea 6000 Series Exhaust Valve 30mm +1mm 2JZGTE Supra MK4
The 6000 Series Competition Valves are designed to provide excellent reliability in an environment of high spring pressures, at a budget price. They have higher fatigue resistance and tensile strengths than our competitor's best offerings.


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.
