- This is a product unique to HKS that enables the installation of blow-off valves in valvetronic engines that do not generate negative intake manifold pressure.
- When released to the atmosphere, the high frequency and sharp operating sound peculiar to SUPER SQV IV greatly appeals its existence.
- By changing the genuine resin charge pipe part to an aluminum pipe, durability has been improved and ventilation resistance has been reduced (see the figure below).
 
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. The Super SQV will support new generations of turbocharged vehicles.
