The HKS SSQV4 Blow-Off Valve Kit delivers the crisp, high-frequency SQV sound the Super Sequential Valve is known for. The valve mounts neatly beside the engine, giving a clean look to the engine bay while maintaining reliable operation.
The kit includes suction-return parts for a fully recirculated setup when required. This helps keep drivability stable and meets regulations where a return system is needed. During HKS in-house testing, no engine stall or drivability issues were observed.
