Thumbs up 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 will need to remove the all air admission,elctrical plugs and more.. no jokes

Good luck

There is a owner of a Frontier (on the Frontier forums) that changed the spark plugs on a 4.0L engine without having to remove the intake plenum. After looking at my Xterra, I realize it will be difficult and will take some patience, but I'm hoping that I don't have to remove the intake.

Unfurtunatly,you will have no choice to remove the intake because it will be impossible to remove the front and middle spark plugs located on the battery side due to their lengths and also wont be possible to get the wrench down the cylinder to remove the sparks..
The 3 plugs on the air filter side will take you about 30 min to replace them and it will take you another 2 hours to replaced the 3 others on the battery side..
Make sure that you have all the necessary tools before doing the job or you will get really fustrated..
good luck
