The TWIN AIR 154222FRX replacement fire-resistant, pre-oiled air filter features a dual-layer open-pore foam design. The coarse outer foam captures airborne dirt, grime and sand, while the fine inner foam provides a second filtration layer to trap smaller particles while maintaining air passage. The filter is pre-oiled with Twin Air biodegradable foam filter oil.
Its adhesive is designed to withstand repeated cleaning, supporting continued use through routine filter maintenance. The filter is smaller than stock to increase air space and circulation around the filter. Fitment includes the 2019 KTM 350 EXC-F, 2019 KTM 450 EXC-F, 2019 Husqvarna FE 250, 2019 Husqvarna FE 350, 2019 Husqvarna FX 350, 2019 Husqvarna FX 450, 2019 Husqvarna FC 250, 2019 Husqvarna FC 350, 2019 KTM 450 SX-F and 2019 KTM 350 SX-F.
