Description
HKS SSQV4 Blow Off Valve
Product Overview: HKS SSQV4 Blow Off Valve is a forced-induction pressure-control component designed to manage excess charge pressure when the throttle closes. This listing is structured around the exact HKS product/SKU so shoppers can match the component to the intended vehicle or build without relying on a generic product-family description.
Vehicle Application: 2023-2026 Nissan 400Z (RZ34)
Driver Benefit: Proper pressure relief can improve transient behavior and help protect the compressor from repeated surge events during shifts and throttle lift.
Recommended Use: Best suited to turbocharged performance applications where the charge system is being upgraded or tuned for higher boost and sharper response.
Technical & Fitment Notes
- Use the HKS part number/SKU as the primary reference when confirming exact configuration and installation requirements.
- Professional installation is recommended when the component affects engine operation, suspension geometry, braking, fuel delivery, or other safety-critical systems.
- Original catalog note: Note: This Blow off Valve vents to atmosphere. Installation requires modification of genuine parts: Harness bracket, cowl top cover, hood ridge cover The HKS SUPER SQV (Sequential Blow-Off Valve) employs a unique two-stage sequential valve structure using primary and secondary valves. It features a differential pressure control system that delicately manages pressure across a wide operating range from low to high boost. Unlike typical blow-off valves, its "relief-less operation system" suppresses relief at high boost, maximizing charge response during repeated boost and release cycles with throttle ON/OFF. Features - Blow-off valves are placed on both banks of the VR30DDTT engine, quickly releasing unnecessary boost pressure from each turbocharger, reducing their load (when the throttle is off). - All parts except the SQV4 main body are in black to highlight the SQV4. Kit Includes: - SSQ
Fitment and specifications can vary by HKS part number, model year, trim, transmission, drivetrain, and market. Confirm the SKU and application before ordering, particularly on modified vehicles.
