TWIN AIR 154222FRX Replacement Fire-Resistant Pre-Oiled Air Filter

Each Twin Air filter is pre-oiled with Twin Air biodegradable foam filter oil, developed exclusively for Twin Air by Chevron Texaco. Independently tested by the most prestigious engineering lab in Germany and was found to be the superior filter oil on the market.

The TWIN AIR 154222FRX replacement fire-resistant air filter is pre-oiled with Twin Air biodegradable foam filter oil, developed exclusively for Twin Air by Chevron Texaco. Its dual-layer foam construction helps capture airborne dirt, grime, sand, and fine particles while maintaining air passage through the filter.

A coarse open-pore outer foam layer catches larger contaminants, while the fine open-pore inner foam layer acts as a second filtration stage for smaller particles. The adhesive is designed to withstand repeated cleaning, supporting continued use and maintenance. The filter is smaller than stock to increase air space and circulation around the filter.

The TWIN AIR 154222FRX fits select 2019 KTM and Husqvarna models, including the KTM 350 EXC-F, KTM 450 EXC-F, Husqvarna FE 250, Husqvarna FE 350, Husqvarna FX 350, Husqvarna FX 450, Husqvarna FC 250, Husqvarna FC 350, KTM 450 SX-F, and KTM 350 SX-F.
