HKS Super SQV IV Recirculating Blow-Off Valve (Silver) - Honda Civic FK7 / FC1 1.5T L15B (2017-2019)
The HKS Super SQV IV (Silver) is a high-performance recirculating blow-off valve developed for the Honda Civic FK7 and FC1 equipped with the turbocharged 1.5T L15B engine (2017–2019). Designed to work with compatible HKS intake and charge-air systems, it routes discharged boost pressure back into the intake system. This configuration may help maintain stable air-fuel ratios, provide more consistent fuel control, and improve drivability, particularly on MAF-equipped vehicles.
Its advanced sequential dual-valve system, combined with the proven pull-type valve design, provides rapid and controlled boost pressure release, helping reduce compressor surge and minimise stress on the turbocharger. The high-rigidity die-cast metal valve and silver-finished die-cast aluminium body deliver excellent heat resistance, outstanding durability, and long-lasting performance even under high temperatures and demanding operating conditions. The distinctive triple-fin insert produces the signature high-frequency HKS blow-off valve sound, while the recirculating design offers quieter operation than atmospheric venting.
Designed for properly matched forced-induction systems, the HKS Super SQV IV is suitable for both standard vehicles and modified performance builds. Its vehicle-specific design provides direct bolt-on installation and OEM-style fitment, making it an ideal upgrade for street and track use.
