The Twin Air Replacement Fire-Resistant Air Filter for Powerflow Kit is designed to provide dependable engine protection and efficient airflow for select 2019 KTM and Husqvarna motorcycles. Manufacturer part number 154222FR, also identified by vendor part number 715-4222FR, this replacement filter is engineered for use with Powerflow airbox systems and offers a precise fit for supported applications.
The filter uses a dual-layer, open-pore foam construction to capture airborne dirt, grime, and sand while maintaining strong air passage. Its coarse outer foam collects larger contaminants, while the fine inner foam traps smaller particles before they can reach the engine. A thick, flat, greaseless sealing ring provides broad contact with the airbox and functions as a breathable gasket for dependable sealing and airflow.
Designed slightly smaller than the stock filter, the Twin Air element allows additional air space and improved circulation around the filter. The specially formulated adhesive withstands repeated cleaning, including cleaning with harsh solvents or gasoline, helping support consistent service life in demanding riding conditions. This product is intended as a replacement filter for compatible Powerflow Kit applications and should be matched to the motorcycle model and airbox configuration before installation.
Fitment includes the 2019 KTM 350 EXC-F, 2019 KTM 450 EXC-F, 2019 KTM 450 SX-F, and 2019 KTM 350 SX-F. It also fits the 2019 Husqvarna FE 250, FE 350, FX 350, FX 450, FC 250, and FC 350. Always verify model and year compatibility before ordering.
