If replacement is required, see a NISSAN dealer 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 log shown in the “NISSAN Service and Maintenance Guide”. Do not reuse spark plugs by cleaning or regapping.

Always replace spark plugs with recommended or equivalent ones.
