REPLACING SPARK PLUGS
If replacement is required, see an INFINITI
dealer for servicing.
Iridium-tipped spark plugs
It is not necessary to replace the iridium-
tipped spark plugs as frequently as the
conventional type spark plugs since they
will last much longer. Follow the main-
tenance schedule in
“
INFINITI Service and
Maintenance Guide
”
, but do not reuse
them by cleaning or regapping.
Always replace spark plugs with recom-
mended or equivalent ones.

.
The filter element should not be cleaned
and reused. Replace it according to the
maintenance intervals. See
“
INFINITI Ser-
vice and Maintenance Guide
”
for mainte-
nance intervals. When replacing the filter,
wipe the inside of the air cleaner housing
and the cover with a damp cloth.
WARNING
.
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 flame if
the engine backfires. If it isn
’
t there, and
the engine backfires, you could be
burned. Do not drive with the air cleaner
removed, and be careful when working
on the engine with the air cleaner
removed.
.
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.
