The Twin Air Air Filter, manufacturer part number 151109 and vendor part number 715-1109, is designed to provide dependable engine protection and efficient airflow for select Kawasaki off-road motorcycles. Its dual-layer foam construction helps capture airborne dirt, grime, sand, and fine particles before they reach the engine, making it a practical replacement filter for demanding riding conditions.
The thick, flat, greaseless sealing ring creates broad contact with the airbox and functions as a breathable gasket to support increased air passage. The coarse open-pore outer foam collects larger contaminants, while the fine open-pore inner foam provides a second stage of filtration without unnecessarily restricting airflow. The filter is slightly smaller than the stock design to promote additional air space and circulation around the filter.
The adhesive is exclusively formulated to withstand repeated cleaning, including cleaning with harsh solvents or gasoline when used according to proper service procedures. This reusable Twin Air filter is engineered for a secure fit and long-term serviceability. It fits 2009, 2010, and 2012–2015 Kawasaki KLX250S models, as well as 1997–2000 Kawasaki KLX300R models. Verify the motorcycle model and year before installation.
