Synapse Synchronic BOV is a fast-acting design that functions as a blow-off, diverter (DV)/bypass and even a pop-off valve. The patented (6,863,260) design eliminates the diaphragm with a multi-tier piston actuator that self-centers under pressure.
This design is intended to significantly reduce or eliminate compressor surge and will not leak boost.
Vehicle specific flanges available along with adaptor flanges for many other BOV manufacturers. Check the drop down list above for options. With the above adaptor flanges, no welding is necessary!
Please note the WRX flange will fit the 08-09 WRX factory flange (not STI).
