Information

The AIRAID 861-399 fits some Ford Mustang Shelby GT500 models. See vehicle applications for details.
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.

November 13, 2015 - Part 861-399
As usual the Airaid products were of high quality and the fitment was great. I have used their cold air intakes on 4 mustangs now and would never hesitate to promote the product!
