The TWIN AIR cylindrical air filter Ø57mm (manufacturer reference 152503) is designed to protect your engine from dust and debris while remaining compact to free up space in the airbox. Its multi-layer foam construction follows the proven principles of Twin Air filters: a succession of foams with different porosities to trap impurities without hindering airflow.
- Triple layer: first airy foam to capture dust and sand, second denser foam for fine particles, and third fire-retardant layer compatible with the removal of the original flame arrestor screen.
- Durable assembly: specific solvent and petrol-resistant adhesive to maintain the cohesion of the foams over time.
- Compact format: reduced dimensions compared to the original element to increase usable volume in the airbox and promote airflow.
- Breathable seal: maximised contact surface for a clean seal with the filter housing.
- Glued construction: eliminates gaps between layers, limiting internal clogging.
Technical specifications: Sleeve diameter 57 mm, Total diameter 110 mm, Length 130 mm, Sleeve length 60 mm. Version: cylindrical filter. Common compatibilities: Yamaha XT 500 (1987–1989).
