The HKS Super SQV IV (Silver) is a high-performance blow-off valve developed for the Mitsubishi Lancer Evolution IV, V, and VI equipped with the turbocharged 4G63T engine. 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. Designed for stable performance across a wide range of boost pressures, it is equally suited to standard vehicles and modified performance builds.
The robust valve construction is engineered to withstand high temperatures and demanding operating conditions, delivering excellent heat resistance, outstanding durability, and long-lasting performance. The signature HKS design also produces the distinctive high-frequency HKS blow-off valve sound, giving the vehicle a sportier character while maintaining fast and reliable operation.
Developed for properly matched HKS forced-induction applications where airflow, fuelling, cooling, and engine management work together, the HKS Super SQV IV features direct bolt-on installation and OEM-style fitment. This makes it an excellent upgrade for enthusiasts seeking reliable performance and the unmistakable HKS sound for street and track use.
