Dirt track and dusty environments may require more frequent replacement to protect engine health.

How do you clean a Walker filter?

To clean a Walker filter:

1. Remove the filter from the engine and gently tap it or use a soft-bristled brush to remove loose debris.
2. Inspect for damage or excessive wear before cleaning.
3. Spray a liberal amount of filter cleaning solution and let it sit for 8–10 minutes to break down dirt and grime.
4. Use low water pressure from a hose or sink (never a pressure washer) and rinse until all soap residue is gone.
5. Place the filter in a sunny or dry spot until completely dry. Avoid using compressed air.
6. Apply a bead of filter oil around the circumference, about ¼ inch from each edge.
7. Allow about 1 hour for the oil to wick evenly. Add a few drops to any missed spots.
8. Once fully oiled, your filter is ready to reinstall.
