This filter features Pro 5R oiled 5-layer progressively finer mesh cotton gauze media for maximum performance. The progressive layering of media allows the filter to flow at high levels even when dirty. aFe performance air filters use a rounded, evenly spaced pleat design which produces more usable filter surface area for increased flow and greater dust holding capacity To allow multiple cleaning cycles, the filter framework is made of 100% pliable polyurethane that does not deteriorate with time or exposure to heat and chemicals.
