Super SQV4 Black Edition Sequential Blow Off Valve

HKS Super SQV (Sequential Blow Off Valve) uses a unique sequential valve structure and a differential pressure control system, which allows for a broad operating range from low boost to high boost. Its Pull-Type relief design ensures stable operation regardless of the amount of boost pressure.

This HKS SQV IV Black Edition Universal Blow Off Valve maximizes charge-response and supports new generations of turbocharged vehicles. Its pressure-charging and pressurized air relief function improves engine performance, while the black edition's sleek coating cleans up the engine bay's appearance.

Unlike factory recirculation valves, the unique & sharp high frequency sound of the Super SQV IV can be noticed. Including a buff-polished casting pipe, it perfectly matches with the appearance created by HKS Intercooler Piping Kit. Elevate your driving experience with the combination of improved sound and appearance.
