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 "Maintenance and schedules" section of this manual. Do not service iridium-tipped spark plugs by cleaning or regapping.
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 a NISSAN dealer for this service.
