Exclusive design for FL5 Civic Type R. Relief-less system and full range of operation gives response and sound.

(When throttle is off) While operating at low boost pressure, it does not relieve at high boost range and maintains the set boost pressure stably. Installed it in a visible space in the engine bay, it significantly improves the overall aesthetic of the engine bay. A suction return hose is included in the kit, making it applicable to safety standards. When venting to atmosphere, the SUPER SQV4's distinctive high-frequency, crisp operating sound makes its presence very noticeable.
