REPLACING SPARK PLUGS If replacement is required, see an INFINITI
dealer for servicing.
Platinum-tipped spark plugs It is not necessary to replace the
platinum-tipped
q A
spark plugs as fre-
quently as the conventional type spark
plugs since they will last much longer.
Follow the maintenance schedule in the
INFINITI Service and Maintenance Guide,
but do not reuse them by cleaning or re-
gapping. Always replace with recommended
platinum-tipped spark plugs. If maintenance is required, see an INFINITI
dealer for servicing.
The filter element should not be cleaned
and reused. Replace it according to the
maintenance intervals. See the INFINITI
Service and Maintenance Guide. When re-
placing the filter, wipe the inside of the
air cleaner housing and the cover with a
damp cloth.
WARNING O Operating the engine with the air cleaner
removed can cause you or others to be
burned. The air cleaner not only cleans
the air, it stops the flame if the engine
backfires. If it is not there, and the en-
gine backfires, you could be burned. Do
not drive with the air cleaner removed,
and be careful when working on the en-
gine with the air cleaner removed.
O Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result
in serious injury.SDI0145D
