TWIN AIR Air Filter - 151121 Kawasaki KX250F/450F

A patented concept, a strict choice of materials and extreme manufacturing quality guarantee that Twin Air filters offer a level of performance and protection unrivaled to date. That is why most top drivers in national and international championships choose this.

• A first layer of air-permeable foam catches dust, sand and impurities
• The second, denser layer of foam traps finer particles while improving airflow
• Specially developed for Twin Air filters, the adhesive that connects foam parts is resistant to various solvents and gasoline
• Twin Air's filters are significantly smaller than the original elements to increase the available volume in the air box and thus improve air circulation. The unique concept of the "breathing seal" guarantees maximum contact surface with the filter housing
• Due to the mutual bonding of the two foam layers, no dust or dirt can penetrate between the two layers. On twin non-bonded filters this can quickly become a problem as particles between the layers restrict airflow, not to mention the damage caused to the cylinder, piston and piston rings when they eventually enter the engine
