When do you change the spark plugs on a Nissan Armada?

Spark plugs on a Nissan Armada should typically be changed every 105,000 miles or as specified in the owner's manual. However, it's advisable to inspect them periodically, especially if you notice symptoms like rough idling, decreased fuel efficiency, or difficulty starting. If the vehicle has a history of heavy towing or extreme driving conditions, changing them more frequently may be beneficial. Always refer to the specific maintenance schedule for your model year for the best guidance.
