TRX Drop-In Air Filter Set – Pair (OEM Box Compatible)

The F.A.S. Motorsports TRX Drop-In Air Filter Set is a pair of high-flow performance air filters designed to replace the factory filter elements in the RAM 1500 TRX's OEM Ram Air intake box. Sold as a set of two filters to match the TRX's dual-inlet air box configuration, each filter features a high-flow cotton gauze or synthetic media construction that allows significantly more air to pass through compared to the restrictive factory paper filters — while still maintaining excellent filtration efficiency to protect the engine from dirt and debris. Unlike a full cold air intake replacement, these drop-in filters retain the factory airbox, which maintains the factory tune compatibility, preserves the clean underhood appearance, and requires no modifications to install. Simply remove the existing paper filters, drop in the FAS high-flow filters, and enjoy improved throttle response, slightly enhanced exhaust and intake sound, and the potential for small horsepower gains — especially when combined with other modifications like a tune or larger intake piping. The filters are washable and reusable, offering long-term cost savings over repeated paper filter replacements, and they're engineered to fit precisely in the OEM filter housing for a secure, rattle-free fitment. This set is an ideal first upgrade for any TRX owner looking for an easy, affordable performance enhancement that can be installed in minutes without any tools beyond what's needed to remove the airbox lid.
