| First off, reformat your profile so it is readable. You might also update it so that it reflects that you now have a turbo car when you see the bold heading. I have the Apexi Blow-off Valves, but I have no experience with the Sard BOVs. Do you have a link to where you found these? I think most people on this site have Apexi's or HKS's. From what I understand, Ash created the DOOLZ dual intake before he went to work at Z1 or while he was there. Z1 continues to sell the DOOLZ though. Ash made some improvements to the original DOOLZ which is now the DOOLZ version 2. I would assume that he made improvements from the original design. But, I don't have the specifics.
