This is for the '05 Frontier, but should be what you're looking for. http://www.clubfrontier.org/forums/f23/how-change-spark-plugs-2005-gen-2-frontier-40507/
It can be complicacated since on some models the spark plugs are difficult to get to but I would recommend to find the spark plugs first and then double check to make sure you know where they are.
They are under the ignition coils. 5/8" socket and 8 " extension.
How do you change the spark plugs in a 1999 Nissan Altima. Can not get socket on the plug.
factory recomends every 30,000 miles or 60,000 if you are running platinum plugs.
I changed the spark plugs on a 1998 Nissan maxima se with the instructions from the car manual. It tellsyou exactly how to change them and it has pictures.
60,000miles
40 dollars.
Where are the spark plugs on a 1996 Nissan maxima?"
The spark plugs in a 2000 Nissan Pathfinder should be changed every 100,000 miles. This is a suggestion done by the manufacturer which is Nissan Automobile Company.
The Nissan frontier would most likely have their spark plugs down deeper into separate chambers. If it is anything like new ford model trucks you have to locate the wires covering them, about an 8 in extention and a 5/8 in spark plug socket.
