Hey guys i purchased 6 new plugs from IOA today 11 bucks each with discount.The job took about an hour give or take 10 min. Sorry i have no pics .

1st remove g35 cover .
2nd on the drivers side remove intake tube or z tube or cai.
3rd work front to back you have to move some of the lines and or wires in the way.

You will need a spark plug socket it was 5/8 i think and an extension about 10"
Take your time not to strip any threads. Also don't drop the little bolts.


Thanks to Pat and Sean at IOA again for the help advice and discount.


I saved a ton of money doing this myself.
