Replacing spark plugs

Iridium-tipped spark plugs

It is not necessary to replace iridium-tipped A spark plugs as frequently as conventional type spark plugs because they last much longer. 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 recommended 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.
