The AIRAID Direct-Fit Replacement Filter is a convenient way to replace your old 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 dry 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.

August 31, 2018 - Part 861-397
I’m giving this a 3 star rating to start with. I’m hoping to raise it to a 4 or 5 after using it for a while. The reason for the 3 stars to start with is due to the fitment problem. It takes some mighty muscle power to get the stock air box lid back on with the Airaid 861-397 filter in place. The lip around the filter is a bit larger than the stock filter, so, it sits on top of the air box lip rather than in. I thought of trimming the Airaid 861-397 filter so it would fit in the box, but decided to leave it because I felt the seal would be tighter. After pressing strongly down on the air box lid and snapping the latches in place, the fit is nice and tight. It just took more effort than I expected. Stay tuned for an update to the performance of the filter. I love the idea of a cleanable filter. I have one in my Mustang cold air intake and I love it there.
