(wiggle) Hey what's up peeps.I was just wondering has anybody ever heard,have,or used a Spiral Max on there intake yet.And if you have what were your dynos, because they advertised many differentials,and it's supposed to add about 30hp and increase fuel effeciency buy at least 30%.For only about $60. Is this to good to be true?
