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.
