Features:
The aFe Pro Guard 7 oiled air filter offers ultimate engine protection. Designed for heavy-duty diesel and off-road automobiles, it performs well in all driving conditions, but the filter particularly excels in extremely dusty environments. Composed of 100-percent polyurethane on all sides, it withstands high engine temperatures.

Five layers of progressively finer, medical-grade cotton gauze and two layers of non-woven polyester fabric with random porosity block 99.7 percent of dirt and grime from clogging your engine. These materials combine with the specially formulated oil coating to provide high-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.
