Designed for turbocharged vehicles equipped with a mass air flow (MAF) sensor, this Dual-Piston Atmospheric Blow-Off Valve V2 delivers fast response, reliable boost control, and the aggressive “whoosh” sound enthusiasts expect — without the drivability issues common with traditional single-piston or diaphragm-style valves.
Designed to work with factory charge pipes and most aftermarket setups using a standard blow-off valve flange or hose-style connection.
Constructed from high-quality billet aluminum, the updated V2 design features revised internals and a fully billet secondary piston for improved durability under high boost and heat conditions. The valve is fully serviceable with a twist-off top for quick maintenance and inspection.
The dual-piston, counter-balanced design helps prevent idle air leaks often found in single-piston valves, reducing the risk of rough idle, stalling, and inconsistent fueling on MAF-based vehicles.
