Have been seeing a lot of not so good feedback on K&N filters on here, and just wondering if there are any oil free performance filters. The vehicle I need it for is a 1995 Mustang GT/5.0L. It has K&N currently on it, and a after market cold air intake which places the filter in the fender well. I can use any 3inch clamp on cone style filter on this intake, and just wanted to see what my options are. I really would like a high flow filter, as this car is about to be far from stock, heads/cam/intake/larger displacement etc., and could use the added air flow. Thanks, Joe
