This is an authentic Kawasaki replacement part, sourced from the original manufacturer for use with gas powered blowers. The element fits into the air filter case and is used to trap dust and debris before the air enters the engine. Over time the filter can fill up and block air flow, so replacing the air cleaner is part of normal maintenance. This item is sold as an individual replacement part.
The metal pan head screw is an original Kawasaki replacement part that is commonly used with backpack blowers. This metal screw is used to secure the air cleaner base assembly to the carburetor. A screwdriver or electric driver is required to install the screw. The screws are sold individually, please note two are required.
