HKS Universal Super SQV Blow off valve (Silver)

The HKS Super SQV4 Universal (silver) is a sequential pull-type blow-off valve compatible with any turbocharged vehicle. Its dual-stage valve structure uses a differential pressure control system so the valve seals tighter at higher boost levels rather than leaking, unlike spring-loaded push-type valves. It vents to atmosphere on throttle lift and produces the characteristic sharp HKS induction note.

Features

• Sequential dual-stage pull-type valve - primary valve opens first for rapid initial discharge; secondary valve opens fully at maximum pressure differential
• Pull-type design - higher boost pressure increases sealing force, eliminating the spring-rate compromise of push-type valves
• Aluminium die-cast body with silver anodised finish
• Metal die-cast secondary valve
• Triple-fin funnel produces the signature HKS blow-off sound
• Vehicle-specific adapter flanges available separately for direct-fit installation

Fitment

• Universal - suits any turbocharged vehicle with an appropriate adapter or custom fabrication at the charge pipe flange

Notes

• This is a universal unit and does not include a vehicle-specific flange adapter. A matching adapter or custom pipe is required for installation.
• Atmospheric vent - vents boost to atmosphere. On MAF-equipped vehicles this can cause idle issues after lift-off unless the ECU is tuned to compensate.
• JDM product: any HKS certification applies to the Japanese market. Check your state's regulations before road use in Australia.
