HKS Super SQV IV Blow-Off Valve for Mazda3 MPS BL3FW
The HKS Super SQV4 Blow-Off Valve is designed for compatible Mazdaspeed Axela BL3FW models equipped with the turbocharged L3-VDT engine.
Its sequential dual-valve structure and differential-pressure control system are designed to provide controlled pressure release across a broad range of boost conditions. The pull-type valve mechanism uses boost pressure to help keep the valve securely closed while the engine is under load.
The SQV4 features a silver-finished aluminium die-cast body, a metal secondary valve and the distinctive HKS triple-fin insert that produces the characteristic high-frequency discharge sound.
