Protect engine performance with the Twin Air Fire Resistant Pre-Oiled Air Filter, manufacturer part number 154224FRX and vendor part number 715-4224FRX. Designed as a replacement filter for select KTM and Husqvarna off-road motorcycles, this filter uses a dual-layer foam construction to provide effective protection against airborne dirt, grime, sand, and fine particles while supporting consistent airflow.
The coarse open-pore outer foam captures larger contaminants before they reach the filter’s fine inner layer. The fine open-pore inner foam traps smaller particles while maintaining efficient air passage for dependable engine breathing. Twin Air pre-oils each filter with biodegradable foam filter oil developed exclusively for Twin Air by Chevron Texaco. The filter oil was independently tested by a leading German engineering laboratory and evaluated for filtration performance.
Built for repeated service, the adhesive is designed to withstand regular cleaning and maintenance. Its smaller-than-stock profile creates additional air space and circulation around the filter, helping support airflow in demanding riding conditions. The fire-resistant construction adds an additional layer of protection for compatible racing and off-road applications.
