The 2014 Honda CRF110F is a renowned youth and pit bike that delivers dependable performance for beginner to intermediate riders. To keep your CRF110F running strong, regular air filter maintenance is essential—ensuring peak engine performance, longer motor life, and superior throttle response. This exclusive MotoSport.com guide gets you through the cleaning and replacement process with easy-to-follow steps tailored for your 2014 Honda CRF110F.

Why the 2014 Honda CRF110F Air Filter Matters

The CRF110F uses a dual-stage foam air filter for superior dust protection and maximum airflow. This feature is crucial since pit bikes often see dusty trails and dirty conditions. The coarse, outer open-pore foam traps larger particles while the fine, inner foam keeps fine dust out of your engine.

When Should You Clean or Replace the Air Filter?

  • Clean after every few rides in dusty, sandy, or muddy conditions.
  • Inspect and clean after every major riding day or race event.
  • Replace if the filter is torn, excessively dirty, or the foam is breaking down—install a high-quality replacement at least once per season for optimal protection.

Tools & Supplies You'll Need

  • Socket set (8mm or Phillips screwdriver for side cover)
  • Clean rags
  • Foam air filter cleaner or mild detergent
  • Fresh air filter oil (specifically for foam filters)
  • Nitrile gloves (optional)
  • OEM or high-performance air filter if replacing

How to Remove the Air Filter

  1. Turn off the bike and let it cool completely.
  2. Remove the seat: Loosen and remove bolts securing the seat with a socket or screwdriver.
  3. Locate the airbox: Found just below the seat.
  4. Open the airbox cover: Remove retaining screws or clips and carefully pull off the cover.
  5. Take out the air filter: Gently pull the foam filter from its cage, noting its orientation for reinstallation.

Cleaning the Air Filter

  1. Tap the filter lightly to remove loose debris away from the airbox.
  2. Submerge in approved foam air filter cleaner or warm soapy water. Squeeze gently (do not wring out or twist, as this can tear the foam).
  3. Rinse thoroughly with clean water until free of dirt and cleaning solution.
  4. Allow the filter to dry completely away from direct sunlight or high heat.

Oiling & Reinstalling the Air Filter

  1. Once dry, pour filter oil across the entire surface. Massage the oil in by hand, ensuring even coverage. The filter should be tacky but not dripping.
  2. Reinstall the filter by reversing the removal process. Be sure the edges seat securely to prevent dusty air from bypassing the filter.
  3. Reinstall the airbox cover and seat. Double-check for a proper seal.

Replacing the Filter

  • If your filter is worn, degraded, or won't clean up, replace it with a new OEM or high-performance option.
  • Filters such as the Twin Air or CJR Performance two-stage foam filters fit the 2014 CRF110F and provide easy installation and reliable dirt protection.

Model-Specific Tips for the 2014 CRF110F

  • The CRF110F's airbox design and intake location means the filter can collect water and mud in extremely wet riding. Check and service after deep water crossings.
  • Always ensure the filter cage is properly secured and seated to avoid dust leaks.
  • The dual-stage design is critical—single-stage filters are not recommended for this model or riding environment.
  • A pre-oiled replacement filter can simplify the job and reduce downtime if you're a frequent rider.

Proper air filter maintenance is the simplest, most effective way to protect your 2014 Honda CRF110F's engine. Make it a habit before every big ride, and your bike will reward you with long-lasting, reliable performance season after season.
