REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-tipped
Aspark plugs as frequently as conventional
type spark plugs because they last much lon-
ger. Follow the maintenance log shown in the
“INFINITI Service and Maintenance Guide”.
Do not service iridium-tipped spark plugs by
cleaning or regapping.
∙ Always replace spark plugs with recom-
mended or equivalent ones.
WARNING
Be sure the engine and ignition switch are
off and that the parking brake is engaged
securely.
CAUTION
Be sure to use the correct socket to remove
the spark plugs. An incorrect socket can
damage the spark plugs.
If replacement is required, it is recommended
that you visit an INFINITI retailer for this
service.
