Frequently Asked Questions

Q: Do I need to apply any extra filter oil before installing this filter?
A: No. This filter is precision pre-oiled at the factory using specialized equipment to achieve the ideal saturation level, meaning it is completely ready to drop into your airbox straight out of the bag.

Q: Can this foam air filter be washed and re-oiled for future use?
A: Yes. Once it gets dirty from track or trail riding, you can clean it using a dedicated foam filter cleaner, let it dry completely, re-oil it with quality filter oil, and reuse it multiple times.

Expert Pro-Tip: When installing a round air filter on modern Honda CRF models, ensure the sealing rim seats completely flush against the airbox flange without any folds or twists. Applying a light layer of waterproof grease around the base sealing ring provides an extra layer of defense against microscopic dust bypassing the element in extreme silt.
