Synapse Synchronic Blow Off Valve is the first to revolutionize the blow off valve industry. Unlike other blow off valves on the market, this BOV does not use a diaphragm which give it unparallel response and eliminates compressor surge. It features a pull type piston actuated design and poppet valve for maximum flow at initial opening. Includes stainless steel weld-on flange. Other flanage available separately.

For cars w/ MAF sensors discharging to atmosphere, an Anti-Stall Valve Kit is available separately.
