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.

your piston rings might be bad
They are under the ignition coils. 5/8" socket and 8 " extension.
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/
factory recomends every 30,000 miles or 60,000 if you are running platinum plugs.
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.
