Five layers of progressively finer, medical-grade cotton gauze block 98.6 percent of dirt and grime from clogging your engine. Furthermore, deep, wide pleats increase the surface area, yielding a high dust-holding capacity. Encased in expandable metal and epoxy-coated aluminum wire mesh, the filter offers flexibility to withstand extreme pressure during races. Multi-layered material provides the highest-performance airflow and extended service intervals. This aFe air filter is washable and reusable; cleaning and re-oiling are recommended once every 25,000 to 30,000 miles.

Note: Upgrading your stock air filter to a performance filter does not change the stock intake tract or emissions output of your exhaust system. Therefore, performance air filters - like this product from aFe - are considered street legal and compliant with emission standards in all states and in Canada.
