Ferrea Honda Prelude (1993 - 2000) Exhaust, 1mm Oversize

Ferrea 6000 Series Exhaust Valve 31 +1mm H22A1 H22A4 Prelude

The 6000 Series Competition Valve 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 Valve we use our exclusive two-step slow forging process using EV8 stainless steel on both intake and exhaust Valve. 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 Valve feature flow improvements to deliver the power needed for today's sophisticated racing engines.
