Proper air filter maintenance is essential for the longevity and performance of your 2025 Honda CRF110F. The latest CRF110F features fuel injection and utilizes a dual-layer foam air filter – chosen for its ability to maximize airflow while providing outstanding filtration and protection against dust, sand, and grime.
Owners benefit from the 2025 Twin Air filter, engineered with coarse open-pore foam on the outside and fine open-pore foam inside, flame-laminated into one robust, functional piece. This design reduces clogging tendencies and improves air volume, promoting efficient engine performance.
Key Notes for 2025 Honda CRF110F Owners
- Dual-stage foam filter offers premium protection for the fuel-injected engine – essential for modern performance.
- Engineered to ensure optimal fit and seal with the airbox, reducing risk of dirt ingress.
- Features a thick, flat foam greaseless sealing ring for maximum contact with the airbox.

How to Clean the Air Filter
- Remove seat and access the airbox. Carefully detach the filter – avoid dirt dropping into the intake.
- Inspect filter for tears, degraded foam, or excessive contamination. Replace if damage is present.
- Wash the filter in a dedicated filter cleaner or mild solvent. Gently squeeze (do not twist) to clear debris and old oil.
- Rinse with clean water and allow the filter to dry completely before re-oiling.
- Apply a high-quality foam air filter oil evenly to cover both layers – avoid over-oiling, which can restrict airflow.
- Install the clean, oiled filter securely, ensuring the seal sits flat against the airbox.
- Reinstall seat and check for proper fitment.
Replacement Guide
