TWIN AIR Standard Air Filter, Kawasaki, 151129FR

Standard Air Filter - Kawasaki

The TWIN AIR Standard Air Filter is designed for select Kawasaki KX450 and KX450X motorcycles. Its dual-bonded foam design filters out small dirt particles while allowing more airflow than two separate filter layers, based on flow bench testing.

The filter is slightly smaller than the stock filter to simplify installation and increase dead air space around the filter for performance benefits. A flat foam sealing ring provides a secure seal against the airbox, including in demanding riding conditions.
