HKS SSQV4 EVO X (08-10); Includes 2 Polished Aluminum Pipes 0E091
HKS Super Sequential BOV V.4 - Mitsubishi EVO X
In 1994, HKS introduced the first Sequential Blow-Off Valve that blazed the auto industry with a unique pull-type sequential valve structure and a differential pressure control system. This advanced system allowed for a broad operation range from low to high boost. This pull-type relief design ensures stable operation regardless of boost pressure.
Super SQV 4 features include a nickel-plated, die-cast metal secondary valve, which is waged to the primary valve, a stainless steel C-Clip and spring to increase sealing and durability. To assure buyers that they are purchasing an authentic HKS product, the new design incorporates a holographic HKS logo on the back of the valve, as well as additional HKS logos cast onto the body structure.
