The Twin Air Air Filter, manufacturer part number 150209 and vendor part number 715-0209, is designed to deliver dependable engine protection and efficient airflow for select Honda motocross motorcycles. Its dual-layer foam construction helps capture airborne dirt, grime, sand, and fine particles before they reach the engine, making it a practical choice for demanding riding conditions.
The filter features a thick, flat foam sealing ring that creates maximum contact with the airbox while functioning as a breathable gasket. Twin Air’s open-pore foam uses a coarse outer layer to collect larger contaminants and a fine inner layer to trap smaller particles without unnecessarily restricting air passage. The filter is slightly smaller than the stock filter to promote additional air space and improved circulation around the element.
Feature: The greaseless sealing ring provides a secure, breathable seal against the airbox.
Feature: Dual-layer open-pore foam captures both larger debris and fine particles.
Feature: Specially formulated adhesive withstands repeated cleaning, including cleaning with harsh solvents or gasoline.
Feature: Slightly smaller-than-stock design improves airflow circulation around the filter.
Feature: Reusable construction supports regular maintenance and off-road riding conditions.
