SZM BERRYLIUM EXHAUST VALVE SEAT SET (12 PCS) NISSAN VR38DETT 26.80 - C17200

High-boost VR38DETT builds often suffer from valve seat recession and head warping due to extreme exhaust temperatures that exceed the limits of factory sintered steel. These high-precision Beryllium Copper (BeCu) seats are engineered to solve this thermal bottleneck by providing a vastly superior heat transfer rate, pulling critical energy away from the valve face to prevent stem stretching and seal failure. Validated for 1,500+ HP applications, this high-conductivity alloy addresses the mechanical problem of "valve bounce" by offering superior impact absorption, ensuring a stable, gas-tight seal even under the most aggressive high-RPM transients
