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
Fuel Fitters
The fuel filter is located in the engine compartment, on the right
center of the tower dashboard. It should be replaced at 60,000 mites
(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.
