HKS SSQV4 Blow Off Valve - Nissan 400Z RZ34 2023+

Description

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:
- SSQV main body
