Up for sale Brand new NGR BOV and adapter flange 2 1/2 . I recently bought this BOV for my setup as u all kno about the Greddy type S being discontinued NGR has manufactured a BOV with the same design and cool sounding air release u can look it up on there website. unfortunately I can't use it because my charge pipe is constructed using a Vband clamp desighn and I didn't want to cut into it so I had to go with a different BOV and now selling this one I paid $160 plus shipping for this BOV not including the flange so save urself some money my loss ur gain !
