I just put a UNI Foam Filter in 06 firebolt. You have to buy the oil for it, but you should be able to clean and reuse. I heard there was supposed to be a drop in the amount of air let in vs. paper, but mine seemed to pick up some pull from it. Make sure to buy the oil if you get one though. Mine came un-oiled and I was stuck waiting for the oil to arrive. You can get one from Amazon I think and have it overnighted if you need it in a hurry.
