This filter features five layers of progressively finer oiled 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 allows for more usable filter surface area, providing increased flow and greater dust holding capacity. This pliable sealing surface conforms to even the most uneven filter housing, making for a perfect filter fit and sealing surface every time. This design eliminates the use of gaskets or sealants and always goes back to its original form. All aFe POWER performance air filters are constructed with a full 360-degree polyurethane frame. This construction allows for a proper factory style fit with excellent filter strength.
