Cleaning Procedure

  • Gently tap the filter to knock loose heavy dirt outside the airbox.
  • Place filter in a bucket with approved foam filter cleaner. Work the solution through all foam layers.
  • Rinse thoroughly with warm water.
    Note: Never use gasoline or harsh solvents – these degrade the bonding glue and foam integrity.
  • Repeat cleaning steps if filter is very dirty.
  • Squeeze (do not wring) out excess water – damaging filter bonds risks engine contamination.
  • Let the filter air dry fully in a ventilated space.

Oiling Your Foam Filter

  • Once dry, apply specialty foam filter oil. Massage oil into every part of the filter – colored oils help you confirm coverage.
  • Aim for even saturation — too much oil restricts air, too little compromises filtration.
  • Apply a light layer of grease around the filter's sealing edge.

Reinstalling on the CRF150RB

  • Carefully fit the filter back into the airbox. Make sure the filter seals fully and evenly around the intake area.
  • Reassemble the airbox cover and seat.
  • Start the bike and check for smooth idle and response.

Replacing Your Air Filter

  • For best performance, replace the filter every season, or at first sign of physical wear or glue seam failure.
  • Choose a dual-stage foam filter designed specifically for the CRF150RB (2007-2025 compatible).
  • Filters like these feature flame-laminated construction: a coarse outer layer traps large debris, while a fine inner layer stops even the smallest particles.
