I have a set of Tial 50mm BOV that i got from GTM motorsports as part of their stage II turbo kit. I went a different route and used them for about 1,000 miles. These are retail for well over 200 even on ebay. im asking $185 OBO w/ shipping for each of them or $350 w/shipping for both. . PM me or send me a text at 812-589-2687.
