HKS is excited to announce its all-new Black Edition of the Super SQV4 Blow-Off Valve with Return Kit for the 2008-2020 Subaru Impreza WRX | STI. The HKS Super SQV (Sequential Blow Off Valve) Kit uses a special valve structure and differential pressure control system to deliver the best results possible. This design is different than other kits on the market and allows for a wider operating range from low boost all the way to high boost. What’s more, this kit supports new generations of turbocharged vehicles, including stock and highly tuned models.
The HKS Super SQV kit maximizes the charge response that repeats pressure charging and pressurized air relief by the throttle on and off. It also ensures stable actuation through the adaptation of HKS’s own sequential valve structure and special pull-type relief design. As aforementioned, the Super SQV can operate across the entire pressure range without leaking – unlike pull-type BOVs out there. At low boost ranges, the primary valve opens; at high boost ranges, the secondary valve also opens, delivering a linear response and optimal blow-off operation no matter the level.
The new Black Edition of the HKS SQV4 Blow-Off Valve with Return Kit features a body and upper part that have been painted in a semi-gloss black color with a wrinkle-black coated funnel. Installing this product on your Subaru WRX | STI will deliver a unique, sharp, and high-frequency SQV sound that suits the sport compact car perfectly. This unit is designed to be located beside the engine to enhance the overall appearance of the underhood compartment and make it stand out at your next show or event.
