Pro GUARD7 Media: This filter features 5-layers of progressively finer oiled cotton gauze and 2-layers of finer porosity synthetic non-woven media for the highest filtration efficiency in extreme dust environments. (US PAT 06811588) Rounded Open Pleats: aFe performance air filters use a rounded, evenly spaced pleat design that produces more usable filter surface area for increased flow and greater dust holding capacity. Progressive Bump Seal: This pliable sealing surface conforms to even the most uneven filter housings. This design eliminates the need for gaskets or sealants. The soft urethane construction always returns to its original form, so you will never compress the bump seal. This ensures a perfect filter fit and sealing surface every time. Full Urethane Housing: aFe Power performance air filters are constructed using full 360-degree urethane frames. This construction allows for a proper factory-style fit with excellent filter strength.
