Guest, New Stock alert: Premium CUPRA valve caps now available in the store ? Order now from the merchandise store
its less restrictive now meaning the air can flow more freely hense the reason i can hear the turbo spool louder
Im pretty sure the small change of half smoothing the air box wouldnt make a difference in sound? It wouldnt effect the air flow THAT much surely..?
will just drilling the airbox without all the rest of it give you an good induction noise???
Would this work on a tdi 150? Louder spooling etc.. Lol...
