The Twin Air Air Filter, manufacturer part number 151338 and vendor part number 715-1338, is designed for reliable filtration and improved airflow on select Kawasaki KLX140 motorcycles. Its thick, flat foam sealing ring creates broad contact with the airbox and functions as a breathable gasket, helping support consistent air passage while reducing the risk of dirt bypass.
Built with a dual-layer open-pore foam design, this filter captures airborne dirt, grime, and sand before they reach the engine. The coarse outer foam collects larger contaminants, while the fine inner foam provides a second filtration stage for smaller particles without unnecessarily restricting airflow. Twin Air sizes this filter slightly smaller than the stock filter to create additional air space around the element and promote improved circulation within the airbox.
The exclusively formulated adhesive is engineered to withstand repeated cleaning, including cleaning with harsh solvents or gasoline when proper service procedures are followed. This reusable design makes the filter suitable for regular maintenance in demanding riding conditions. The greaseless sealing ring also simplifies installation and helps provide a secure fit against the airbox.
Fitment: Fits 2008, 2009, and 2011–2018 Kawasaki KLX140 motorcycles. Verify the motorcycle model year and airbox application before installation.
