The 2013 Honda CRF110F features a dual-stage foam air filter design that ensures superior filtration while maintaining strong airflow for reliable engine performance.–1–2–5 Proper air filter maintenance is crucial, especially when riding in dusty or wet environments, as the CRF110F’s compact airbox is sensitive to debris buildup.

When to Clean or Replace the Air Filter

  • Factory guidance: Clean the air filter every 6 months or sooner depending on ride conditions. For dusty areas, cleaning is needed every few rides.
  • Indicators: If you see dirt, oil saturation, tears, or the foam is crumbling, cleaning or immediate replacement is necessary.–3

Tools & Supplies Needed

  • 8 mm socket or wrench
  • Cleaning solvent (specifically for foam filters, if possible)
  • Foam air filter oil
  • Rags and gloves
  • Replacement dual-stage foam filter (if damaged) – OEM or trusted aftermarket part

How to Remove the Air Filter

  1. Turn off the engine and ensure the bike is cool.
  2. Locate the air filter: On 2013 CRF110F, the airbox sits up front behind the fender. No fender removal is required.–3
  3. Remove the four cover bolts with the 8 mm wrench.
  4. Lift off the airbox cover and access the air filter element.
  5. Carefully remove the filter. Keep debris out of the intake tract during removal.

Cleaning the Air Filter

  1. Inspect for damage: If the foam is torn or degraded, replace the filter.
  2. Rinse the filter in warm, soapy water. Work the dirt out gently without twisting or stretching the foam.
  3. Rinse with clean water. Repeat if necessary until the water runs clear.
  4. Gently squeeze out excess water. Allow to air dry completely – avoid direct sunlight and heat.
  5. Once dry, apply foam filter oil evenly. Massage oil throughout the filter without oversaturating.

Reinstalling the Air Filter

  1. Clean the inside of the airbox and the cover thoroughly with a rag and contact cleaner. Remove all residual dirt and oil.–3
  2. Check the airbox drain plug for accumulated oil or water – empty if needed.
  3. Install the clean, oiled filter back onto the cage.
  4. Fit the filter assembly securely into the airbox, ensuring the seal is full and even.
  5. Refit the cover and tighten the bolts evenly. Do not overtighten.
