The HKS Super SQV4 (Black Edition) is a blow-off valve engineered to enhance the performance and aesthetics of specific Subaru WRX STI models equipped with the EJ20 turbo engine, fitting model years from 14/08 to 20/04. It utilizes HKS's unique sequential valve structure and a pull-type relief design, ensuring stable actuation and optimal performance from low to high boost pressures. This "Black Edition" variant presents a sophisticated appearance, featuring a semi-gloss black painted body and upper section, complemented by a wrinkle black painted funnel. The kit includes the necessary suction and return components and is specifically configured for the targeted vehicle, contributing to improved charge response by managing pressure-charging and air relief effectively. Installation of the HKS Super SQV4 creates a distinctive, sharp, and high-frequency "SQV" sound, signaling its performance enhancement. The SQV IV unit's design allows for placement beside the engine, further improving the overall engine bay's appearance.
