Go with GFB. They’re far better in sound and the ADD W1 is a rather odd install. For ease of removal for any warranty work (because dealers love fo blame aftermarket BOVs for blown turbos), GFB makes it much easier. I am not affiliated with them but I’ve just used GFB and Add W1. If you have Facebook, I know someone that can get you a great deal on some BOVs and probably Dragy as well. PM me if interested.Looking for any BOVs (preferably ADD W1 red) and a Dragy at a decent price thanks
I have turboxs for sale if you need a set
