This AIRAID Direct-Fit Replacement Filter is a drop-in replacement for your vehicle's stock paper air filter that is designed to improve horsepower and acceleration. The air filter is constructed with multiple layers of filter media and provides significant improvements in air flow and filtration compared to typical replacement filters with the added benefit of being washable and reusable. Why throw money away on a paper filter each time the old one gets dirty when you can upgrade to a serviceable AIRAID Direct-Fit Replacement Filter for often less than the cost of two stock replacements? Installation takes only minutes and is as simple as replacing your stock filter.
