Does anyone know anything about Fram's new " Air Hog " performance filters? I just saw an ad in my new Car and Driver mag. the other day and was wondering if it would be worth trying until I can afford an intake. It sounds similar to a K&N ( oiled cotton gauze ), but I was wondering what kind of power and mileage gains to expect. I've never been a big believer in Fram products, but I thought I might give this a try.
