Air Cleaner Element
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 cover.
Remove the air cleaner element and
replace it with a new element. Reinstall
the cover and tighten the bolts.
Fuel Filter
The fuel filter is located in the engine compartment, on the right center
of the rear bulkhead. It should be replaced at 60,000 miles (96,000 km)
or 48 months whichever comes first, or any time you suspect
contaminated gas may have clogged it.
CAUTION: Because the fuel system is under pressure, the filter
should be replaced only by a qualified Honda technician.
