Just read this thread and realized nobody has mentioned this, although it is not required, it is still a useful tip used on any vehicle;
When replacing spark plugs, get a piece of rubber hose that fits snug on the plugs.
It can be used to remove them from the head and not dropping them if you don't have a magnetic socket, but the main reason would be when threading them back in, as cross-threading a spark plug in an aluminum head is never a great thing!
Using the hose to get the first few threads in insures you're threading correctly as the hose will simply slip on the plug if there is some resistance from the threads not going in correctly.
Plus, it sometimes makes it easier to get them in place in tight areas, as dropping or knocking a plug hard enough on something may affect its gapping!
Not a bad idea, but you should always use a tool designed for the job (i.e., spark plug socket shown in my original post), imo. It prevents the plugs from falling out. Plus, you want to hand thread it in initially and not jump right into threading your new plugs with a socket so no worries on cross threading.
My '03 touring has the original spark plugs and I have 78k on the odo. Am I good till 100k still or should I just replace them anyway since it's been 11 years? After driving around and putting my car in neutral the engine sometimes stalls (dashboard still lit) but I thought maybe the spark plugs are going?
Hey guys this is my first post, I have a 07 350z and I spent hours removing my bumper, injen long tubes, and everything necessary to get to the spark plugs and finally got to it. I keep turning the socket and the plugs just keep turning and Ive been at it for an hour. Is there any way I can remove the spark plugs. I tried to remove all of them and they all just keep turning but won't come out. Thanks I really appreciate any help
hey again, ya I used a 5/8 spark plug socket and a ratchet w/ long extension and it just keeps turning and turning and none of the spark plugs will come out
Just ordered me some new spark plugs... Figured I might as well because they are probably original 12 year old plugs, I went with the 1 step colder so hopefully my car enjoys them
Thanks OG #1 for the detailed instructions and information.

Not sure if anyone follows this thread anymore, I just bought my 2004 z pretty new to it , how many spark plugs are in the engine? Do they have a specific size for the plugs , how do I prevent misfires ??

6 spark plugs. One for each cylinder. Standard replacement is NGK PLFR5A-11. Gap is 1.1 mm (0.043 in). Recommended replacement is every 105,000 miles.
