Air Cleaner and Fuel Filters Air Cleaner Replace the air cleaner element every 24 months or 30,000 miles (48,000 km), whichever comes first (more often in extremely dusty conditions). Loosen the attaching bolts, then remove the air cleaner housing cover. Remove the air cleaner element and replace it with a new air cleaner element. Reinstall the cover and tighten the bolts. BOLTS AIR CLEANER ELEMENT Fuel Filters The fuel filter is located in the engine compartment, on the right center of the lower dashboard. It should be replaced at 60,000 miles (96,000 km) or 48 months whichever comes first, or any time you suspect contaminated fuel may have clogged it. Because the fuel system is under pressure, the filter should be replaced only by a qualified Honda technician.
