GFB's adjustable blow off valve allow for infinite adjustment between complete recirculation and complete vent-to-atmosphere. This allows the owner to choose, with a flick of the wrist, how loud they want their blow-off valve to be.
Great item. Easy to install and love that it’s easily adjustable. Makes a great sound
My bov is currently set to 50/50 and it goes off from 3rd gear up, @ 3000 rpm and greater it sounds good and is discrete when needed.
Super easy to install and sounds great!! Many PPSSSSHHHHHHs to be had!
Wise words I learned the hard way.... PUT THE CLAMP ON THE RECIRC HOSE BEFORE YOU BOLT THE BOV ON!!!
Awesome part, fits perfectly, sounds great and is super loud at 100% to the atmosphere and still has an awesome sound on full recirculation. I personally keep mine at around 50/50 and couldn’t be happier with it.
My car now goes Stutututu and Psssss what more can you ask for, great product!
