Unique Features of the 2018 KTM 500EXCF Air Filter System
- Extra-large Twin Air filter: This model uses a high-capacity filter for improved airflow and filtration. The rigid mounting cage secures the filter reliably, decreasing the risk of poor sealing in muddy or dusty environments.
- Tool-free access: The filter can be accessed, removed, and replaced with no tools required – a quick maintenance advantage, especially on muddy rides or during racing events. The air filter housing prevents clogging and makes servicing straightforward, even with gloves or if your hands are dirty.
Step-by-Step Air Filter Cleaning Instructions
- Remove the seat: Release the seat latch and slide the seat backward to access the airbox.
- Remove the air filter cover: Unlock the side panel and carefully take off the cover to expose the filter.
- Extract the air filter: Gently pull the filter with the cage assembly out of the airbox.
- Inspect for damage: Check the filter foam for any tears or signs of deterioration. Replace if you find any damage to prevent dirt entering the engine.
- Clean the filter: Submerge the filter in an approved filter-cleaning solution. Agitate to remove dirt; avoid using gasoline or harsh chemicals which can damage the foam.
- Rinse and dry: Rinse thoroughly with clean water and gently squeeze (do not wring) out excess water. Allow it to air dry completely before re-oiling.
- Apply filter oil: Liberally coat the clean, dry filter with foam filter oil. Massage the oil evenly into the foam, ensuring all surfaces are covered for complete protection.
- Clean the airbox: Wipe out dust and debris from the airbox using a damp cloth, taking care not to let anything drop into the intake tract.
- Reinstall the filter: Place the filter and cage back into the airbox, ensuring a secure fit. Reattach the air filter cover and seat.
When to Replace the Air Filter
- Replace the air filter if the foam shows tears, is extremely dirty after cleaning, or does not return to its original shape.
- High-quality replacements, like Twin Air or Uni filters, offer two-stage foam design for optimal dust and dirt retention and endurance riding protection.
Pro Tips Specifically for the 2018 KTM 500EXCF Owner
