From what I have seen the intakes that LXguy has are not uncommon. I have a friend who had a crosswind that actually broke when he was tightening it down, he had used it on several different engines previously, anyway the ports looked a lot like the ones pictured here. I have to believe that robs power since I have a basic understanding of fluid dynamics. There is a reason that I bought an eddy, lol well two reasons, I want more power and I try to buy made in USA.
