Replacing spark plugs

Iridium-tipped spark plugs (if so equipped)
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 “NISSAN Service and Maintenance Guide”. Do not service iridium-tipped spark plugs by cleaning or regapping.
● Always replace spark plugs with recommended or equivalent ones.

Be sure the engine and ignition switch are off and that the parking brake is engaged securely.

Be sure to use the correct socket to remove the spark plugs. An incorrect socket can damage the spark plugs.
If replacement is required, see your NISSAN dealer for assistance.
