I have seen this problem as well with the foam filters. I even had a guy put one on his car and it idled up because it richened it up that much. I have a customer that took his oval air cleaner and made him a new bottem that was dropped so he could get a 4 inch element under his hood and still get the engine good air flow. I hope I can get him to do one for me as well. I see a lot of the Cobra's with what looks to be to small an air filter. Good luck, Keith
