The accu-air valves are very clean and compact. I have done there new system in 2 cars now. It works so good!!!! It is with-in a 1/16" every time! I have there old system and am going to upgrade to there new system and valves. I have Extreme 1/2" Valves..... I don't like them. They get stuck, leak etc. The Accu Air do not leak! They sound cool too.
