BOV-12(similar to SSQV)

Application:

Universal the BOV-12 is a dual stage pull-type relief vale.Unlike typical push type blow off valve.The BOV-12will not leak under any level of boost because the boost pressure in chamber keeps the valve closed against its seat.

The dual stage pull valve will open under part throttle light boost.and vent through the first small port creating a high pitch whistle, at higher boost full throttle, the 1 st port opens the 2nd port amd will creat the lound PPPPSSSSHHHH sound ,

This BOV-12is one of the most recognized blow off valve they ever made.
