HKS Super SQV IV Blow-Off Valve (Silver) - Nissan Skyline GT-R R33/R34 RB26DETT (1995-2001)
The HKS Super SQV IV (Silver) is a high-performance blow-off valve developed for the Nissan Skyline GT-R R33 and GT-R R34 equipped with the legendary RB26DETT 2.6-litre twin-turbocharged engine. Its advanced sequential dual-valve system, combined with HKS differential pressure control, provides rapid and controlled boost pressure release across a wide range of boost conditions. The proven pull-type valve design uses boost pressure to keep the valve securely sealed under load, helping reduce compressor surge and minimise stress on the turbochargers.
The valve features a silver-finished die-cast aluminium body paired with a durable die-cast metal secondary valve, ensuring excellent heat resistance, outstanding durability, and reliable operation even under demanding boost levels. The distinctive triple-fin insert produces the signature HKS blow-off valve sound, giving the vehicle a true motorsport-inspired character. Optional replacement sound inserts are also available for selected applications, allowing further sound customization.
Designed for compatible RB26DETT applications, the HKS Super SQV IV offers direct bolt-on installation and OEM-style fitment. Suitable for both standard vehicles and modified performance builds, it is an excellent upgrade for enthusiasts seeking improved performance, quicker boost response, and the unmistakable HKS sound for street and track use.
