HKS Super SQV IV Blow-Off Valve for Nissan Skyline R33 R34 RB25DET
The HKS Super SQV4 Blow-Off Valve is designed for compatible Nissan Skyline R33 and R34 models equipped with the turbocharged RB25DET engine.
Its sequential twin-valve structure responds across a broad range of boost pressures, helping release excess pressure from the intake system when the throttle closes.
The pull-type valve design uses boost pressure to support secure sealing, allowing stable operation from low-boost road driving through to higher-performance applications.
