The Twin Air Air Filter, manufacturer part number 158033, is designed to provide dependable engine protection and efficient airflow for select Beta motorcycles. Its thick, flat foam sealing ring creates maximum contact with the airbox while functioning as a breathable gasket, helping increase air passage around the filter. The filter is slightly smaller than the stock design to promote improved air circulation within the airbox.
A coarse open-pore outer foam layer captures airborne dirt, grime, and sand before they reach the engine. A fine open-pore inner foam layer provides a second stage of filtration for smaller particles while maintaining strong airflow. The exclusively formulated adhesive is engineered to withstand repeated cleaning, including cleaning with harsh solvents or gasoline, helping support long-term serviceability.
This Twin Air filter fits 2015 Beta 390 RS, 2015 Beta 500 RS, 2016 Beta 500 RS, 2015 Beta 390 RR, 2016 Beta 390 RR, 2015 Beta 430 RR, 2016 Beta 430 RR, 2015 Beta 480 RR, 2016 Beta 480 RR, and 2013 Beta 250 RR 2T models. Verify the motorcycle model and year before installation to ensure proper fitment. The manufacturer part number is 158033, and the vendor part number is 715-8033.
