Platinum-tipped spark plugs
It is not necessary to replace platinum-tippedA
spark plugs as frequently as conventional type
spark plugs because they last much longer. Fol-
low the maintenance log shown in the “NISSAN
Service and Maintenance Guide”. Do not service
platinum-tipped spark plugs by cleaning or re-
gapping.
● Always replace spark plugs with rec-
ommended or equivalent ones.
