SZM BERRYLIUM INTAKE VALVE SEAT SET (12 PCS) NISSAN VR38DETT 31.80 - C17200

In high-performance VR38DETT engines, intake valve seats are subjected to extreme cylinder pressures and mechanical stress that can lead to seat distortion and improper valve sealing. Factory seats often lack the necessary thermal conductivity and impact resilience required for sustained high-RPM operation in boosted R35 applications. These high-precision Beryllium Copper (BeCu) intake seats are engineered to solve this bottleneck by providing a validated increase in thermal dissipation and superior damping properties. This addresses the mechanical problem of "valve seat bounce," ensuring a consistent, gas-tight seal that maximizes volumetric efficiency and protects the valvetrain during 1,500+ HP transients.
