The air filter on your 2013 Honda CRF150R is critical for protection and engine performance. Proper care extends the life and power of your bike – neglecting it can lead to power loss and costly repairs. This guide details everything you need to know for cleaning, maintaining, and replacing the CRF150R’s air filter, plus specific tips for this model year.

Understanding Your 2013 CRF150R Air Filter

  • Type: Dual-stage, open-pore foam filter.
  • Design: Coarse outer foam traps large particles; fine inner foam stops smaller contaminants while allowing high airflow. This design is proven to increase power and protect the engine, especially important for the high-revving, performance-oriented CRF150R.
  • Popular Options: Twin Air and Tusk filters are reputable, built specifically for your model to endure harsh riding conditions and frequent maintenance cycles.

When to Service the Air Filter

  • Inspect after every ride in dusty or muddy conditions.
  • Clean every 5-10 hours of riding, or sooner if dirty.
  • Replace if there are tears, excessive dirt, or if the foam structure is degrading and unable to be cleaned fully.

How to Remove the Air Filter

  1. Put the bike on a stable stand and remove the seat using the OEM seat bolts.
  2. Locate the airbox beneath the seat.
  3. Carefully unclip the retaining bracket or unscrew the fastener holding the air filter cage.
  4. Gently pull out the air filter – avoid dropping dirt into the air boot.
  5. Stuff a clean cloth loosely in the intake to keep out debris during cleaning.

Cleaning the Air Filter

  1. Remove the filter from its cage.
  2. Pre-clean: Tap or gently squeeze (do not twist) to remove loose debris.
  3. Wash: Submerge in a bucket of warm, soapy water (use biodegradable detergent or filter cleaner). Massage filter to release dirt. Repeat in clean water.
  4. Rinse thoroughly with clean water.
  5. Squeeze (never wring) out all excess water – avoid damaging the foam.
  6. Air dry completely, away from direct sun or high heat.
  7. Inspect thoroughly for tears, seams, or glue failures. Replace if compromised.

Oiling the Air Filter

  1. Use only foam filter oil (never motor oil). Pour a small amount into a clean bag or container and coat the entire filter. Work oil evenly through foam until every part is colored; do not oversaturate.
  2. Let the filter sit for at least 10 minutes to allow the oil to distribute and excess to drip off.
  3. Wipe off any excess oil and ensure the sealing edge remains clean for a perfect fit.

Reinstalling the Air Filter

  1. Place the clean, oiled filter back onto the cage.
  2. Remove the rag from the intake boot.
  3. Carefully slide the filter assembly into the airbox, ensuring a tight seal against the airbox rim. Secure with the retaining bracket or fastener.
  4. Double-check for gaps or misalignments – these can allow dirt into the engine.
  5. Reattach the seat securely.

Replacement Tips for the 2013 CRF150R

  • Stick with dual-layer filters designed for your CRF150R. Twin Air and Tusk manufacture high-quality, model-specific filters engineered for Honda's performance standards.
  • Do not substitute automotive or non-motorcycle foam – the CRF150R's high airflow demands and dirt exposure require bike-specific filtration.
  • Check the sealing surface closely. The 2013 CRF150R uses a thick, flat, greaseless sealing ring to maximize contact – ensure no dirt or sand builds up in this area.

Noteworthy Model Considerations

  • The CRF150R is built for MX & aggressive trail use. Filters may require more frequent service than leisure models, especially in races or group rides.
  • If you upgrade your exhaust or increase jetting, clean the filter even more frequently, as increased intake flow will clog a dirty filter faster.
  • Always carry a spare, clean, and oiled filter in a sealed bag for quick swaps between motos.

MotoSport Pro Tips

  • Label multiple filters by service date if you pre-clean and oil them at home.
  • Replace the air filter cage gasket (if equipped) whenever the seal shows wear.
  • If you ride in extreme dust, consider sealing the rim with a bead of waterproof grease for added protection during long events.

A properly maintained air filter prolongs your 2013 CRF150R’s life and ensures maximum performance on the track or trail. Routine care is the best insurance for your bike’s high-revving engine – and that MotoSport has all your OEM and performance parts ready for your next service.
