Its thick, flat, greaseless sealing ring creates broad contact with the airbox while functioning as a breathable gasket, helping maintain a secure seal without restricting air passage.\u003c\/p\u003e\u003cp\u003eThe filter uses a dual-layer, open-pore foam construction. The coarse outer foam captures airborne dirt, grime, and sand, while the fine inner foam provides a second stage of filtration for smaller particles. This design supports clean airflow and consistent engine performance in demanding riding environments. The exclusively formulated adhesive is built to withstand repeated cleaning, including cleaning with harsh solvents or gasoline, helping extend service life when the filter is maintained properly.\u003c\/p\u003e\u003cp\u003eTwin Air makes this replacement filter slightly smaller than the stock filter to promote increased air space and improved circulation around the filter element.
