Step-by-Step Removal – Cleaning Instructions
-
Remove Seat – Cover: Remove the two rear seat screws. Lift off the seat and unsnap the middle black lid with the intake snorkel to access the air filter assembly.
-
Take Out Filter: Loosen the wing nut by hand. Slide out the filter and cage.
-
Inspect – Clean Air Boot: Wipe the air boot with a clean, damp towel to remove any fallen dirt or dust.
-
Extract Filter from Cage: Separate the foam element from its plastic cage.
-
Clean the Filter: Submerge the foam element in a bath of high flash-point solvent or foam filter cleaner. Use a soft brush to gently agitate dirt. Squeeze out the solvent using a clean towel (never wring or twist, as this can damage the element).
Never use gasoline or low flash-point solvents due to fire hazard – only use recommended cleaners. -
Rinse – Dry: Rinse with clean water until the water runs clear. Squeeze dry gently, then let the filter air dry naturally. Never use compressed air or direct indoor heat.
-
Re-Oil: Once totally dry, saturate the filter evenly with high-quality foam air filter oil. Squeeze out excess oil, wrap in a clean rag, and squeeze further until evenly distributed.
-
Reinstall: Re-fit the foam element onto the cage. Carefully seat the filter assembly back into the airbox. Tighten the wing nut by hand.
- Replace Seat – Cover: Snap the cover, replace the seat, and tighten rear screws.
Signs You Need Replacement

Model-Specific Notes for 1997 KDX220 Owners
