The Twin Air Air Filter, Part Number 151120, is designed for Kawasaki KLX450R motorcycles from 2008 through 2012 and 2016 through 2020. This replacement filter is engineered to provide reliable engine protection while supporting efficient airflow for off-road riding conditions. Its slightly smaller-than-stock design creates additional space around the filter, helping improve air circulation within the airbox.
The Twin Air dual-layer foam construction combines coarse open-pore outer foam with fine open-pore inner foam. The outer layer captures airborne dirt, grime, and sand, while the inner layer provides a second barrier against finer particles without unnecessarily restricting air passage. A thick, flat, greaseless sealing ring helps maximize contact with the airbox and functions as a breathable gasket for a secure, effective seal.
Built for repeated maintenance, the exclusively formulated adhesive withstands regular cleaning, including exposure to harsh solvents or gasoline. This reusable design is well suited to demanding riding environments where dependable filtration and serviceability are essential. The manufacturer part number is 151120, and the vendor part number is 715-1120.
