I got a 08 Bullitt and I cant find a replacement/reusable filter for it anywhere. I looked through every filter companies catalog known to man. I chopped up a knn filter that was close in specs, but i'm afraid of it not sealing right. If anyone knows of a place that sells a replacement/reusable filter for my car please let me know. Just in case you dont know about the bullitt, it comes stock with a cold air from ford racing and the filter it comes with is junk, so please dont leave smart ass remarks.
