Iridium-tipped spark plugs
It is not necessary to replace the iridiumtipped 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.
