FHSJXR Outer & Inner Air Filter Set for Kawasaki/Kohler Engines (11013-7044/11013-7045)

Premium air filtration for your outdoor power equipment

The FHSJXR dual-filter set combines an outer air filter with an inner air filter to replace common OEM parts on Kawasaki and Kohler engines. The outer filter is designed to block large debris like grass clippings and sand, while the inner filter targets fine dust and pollen. This dual-layer design can help maintain smooth engine intake and consistent performance by allowing clean air to reach the combustion chamber.

Crafted from premium filter paper and a durable metal mesh, the outer and inner components are engineered to work together without restricting airflow. This setup is designed to deliver unobstructed air passage while providing robust filtration, which may contribute to a steadier idle, steadier power delivery, and better overall engine operation under typical mowing conditions.
