REPLACING SPARK PLUGS
If replacement is required, see an INFINITI
retailer 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

them by cleaning or regapping.
Always replace spark plugs with recom-
mended or equivalent ones.
