Good To Know

Q: When should I replace this air filter kit? A: Replace the outer and inner elements when the air filter service indicator shows a restriction or after the recommended operating hours stated in your equipment manual. Always inspect both filters at each oil change and replace them as a pair to maintain consistent airflow.

Q: Can I clean and reuse these filters? A: No, these are dry-type disposable filters and should be replaced with new elements. Attempting to clean them can damage the media and allow unfiltered air into the engine.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
