I was referring to post number 51 as well. I never said that the guy that started the thread didn't have a problem. He just handled it incorrectly from the start IMO. Those intakes are fitting under most hoods with no problems at all. The post in # 51 states that he is SC , switched to Fox lake and saw no gains. He called and they said he installed wrong. I say, there may be a little more to it. I even asked for before and after numbers. They weren't provided. Back up your accusation, with a little evidence and I have no problems with it. Most every other car tested with SC and P51 showed gains over stock intake and plenum.
