Airaid 09-13 Ford F-150/250/350 Expedition 4.6/5.0/5.4/6.8L Direct Replacement Filter - 860-397

The AIRAID Direct-Fit Replacement Filter is a convenient way to replace your vehicle's stock paper air filter with one that is designed to improve horsepower and acceleration. It replaces the stock panel air filter with a drop-in design that utilizes the area inside the existing air box. Multiple layers of oiled filter media provide significant improvements in air flow and filtration compared to typical replacement filters. More filter surface area also means long intervals between cleaning. Installation takes only minutes and is as simple as replacing your stock filter.
