Spark plugs Xterra 2006
Xterra 2006 4wd V6-4.0L
i just replaced the spark plugs and FYI, the one that were installed by the factory are the NGK PLFR5A-11 with a gap of 0.40
The maintenance manual says that you can change them at 100000+ miles but mine have been runing for 80000 miles and they were good for the trash..
Tips if you decide to do the job yourself... Have the proper tool and be patient because it is going to be a 2-3 hours job process because of the 3 plugs that a located on the batterie side..you will need to remove the all air admission,elctrical plugs and more.. no jokes
