1999 Ford 7.3L Powerstroke AFE Replacement Air Filter
AFE media is constructed of medical grade cotton gauze that is progressively finer from the outside in and laid up to maximize overlap between layers. AFE media stops dirt by directing the air stream through a gauntlet of progressively finer media layer. Dust grabbing microfibers extend into the airstream from each other. Unlike OE filters that only collect dirt on the surface, aFe collects dirt on multiple layers.
