HKS Super SQV IV Blow-Off Valve (Silver) - Honda Civic FK7 / FC1 1.5T L15B (2017-2019)
The HKS Super SQV IV (Silver) is a high-performance blow-off valve developed for the Honda Civic FK7 and FC1 equipped with the turbocharged 1.5T L15B engine (2017-2019). This version is designed for atmospheric venting and is supplied without a recirculation tube. Its advanced sequential dual-valve system, combined with HKS differential pressure control, provides rapid and controlled boost pressure release across a wide operating range, from low to high boost levels.
The proven pull-type valve design uses boost pressure to keep the valve securely sealed under load, minimising the risk of boost leakage while helping reduce compressor surge and stress on the turbocharger. The design may also contribute to quicker boost response depending on the engine setup, while producing the signature high-frequency HKS blow-off valve sound, giving the vehicle a noticeably sportier driving character and an enhanced driving experience.
Developed for properly matched HKS forced-induction applications, the valve is engineered to withstand high temperatures and demanding operating conditions. Its vehicle-specific design provides direct bolt-on installation and OEM-style fitment, making the HKS Super SQV IV an excellent upgrade for both standard vehicles and modified turbocharged builds, suitable for street and track use.
