About this product

Part #: 851-031

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.

What made you choose this particular product?
Cheap upgrade with adequate performance
What were you trying to accomplish by adding this product?
Better air flow for intake
Was it easy install? Any installation tips that will help others?
Super easy to install. It fits over the bottom half of the factory air box and the factory intake hose.
Once you’ve had a chance to use the product, did it meet your expectations?
Yeah, it works exactly as it should.
Any additional comments?
Since it fits over the bottom half of the factory box, it still gets cooler air than your average cone c.a.i would. A relatively cheap mod with decent gains for what it is
