8-20 Maintenance and do-it-yourself
REPLACING SPARK PLUGS
If replacement is required, see a GT-R certified
NISSAN 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 maintenance schedule in NISSAN
Service and Maintenance Guide, but do not
reuse them by cleaning or regapping.
Always replace spark plugs with recom-
mended or equivalent ones.
Remove the retainers

The filter element should not be cleaned and
reused. Replace it according to the maintenance
intervals. See NISSAN Service and Mainte-
nance Guide for maintenance 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.
