Intake and Exhaust Valves are One Piece Forged, High Temperature, High Nickel, Stainless Steel Alloy. Valves are CNC finished to strict tolerances making these valves the choice for the most demanding race classes.
These valves can only be fitted to your 4G63 head with new larger inlet valve seats. The standard seat cannot be cut for this larger item. This increases installation cost considerably so is only needed on the very high end engines.
(Price Shown is per Valve)
