I have a real Tial BOV. I just sent the bov back to Tial to check and see if there were any problems with it and they said everything was good to go, i have the paperwork from that. Looking to get 130 OBO. I dont have the flange, o-ring, or clamp but you can get them from this site for cheap. http://www.nipponpower.com/product.phtml?p=484
