WARNING
Be sure the engine and the 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.
REPLACING SPARK PLUGS
If replacement is required, see an INFINITI re-
tailer 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
“INFINITI Service and Maintenance Guide”, but
do not reuse them by cleaning or regapping.
Always replace spark plugs with recommended
or equivalent ones.
