When do I need to replace the spark plugs?!?
hello guys...
got a noob question here...
I have done some search but i cant seem to find the answer...
at what mileage or timeline do I need to replace the spark plugs for my 2004 G35 5AT??
I have looked through the service manual as well as Infiniti help website but neither one indicates the time/mileage when the spark plugs need to be replaced....
is it something that's totall up to owner's choice?!
and also.. what benefit would it give to me to replace the spark plugs?? bettter gas mileage, gaining loss hps?????
and last question.. What's a reasonable price to have someone other than the dealership done the job for me (labor + parts)......
thanks in advance for your inputs...

It's tight alright and the coil on plug makes it even more difficult. It is do-able with a little experience and patience, tho.
Altho the manufacturer recommends changing them at about 100k, I'd change them at 50-60k for optimum performance (read gas mileage) since by 100k plugs will be well past their peak.
LOL, with gas prices rising the way they are these days, and the expected 'skyrocket' by spring, it would seem a prudent investment.
A caution: If you do the change yourself, be very careful removing the old plugs. They've been sitting in aluminum heads for years and many kilometers and could easily break or damage delicate threads.
Don't forget a coating of anti-seize on the new threads to help with their eventual removal.

I took my Coupe plugs out once to check the threads and gap and it took me a good 2hrs due to plumbing and such.

because if it is 5 hours of labor and they are charing around $95/hour.. then i am looking at around $475 for the labor and say $50 for the parts..and that's ridiculous..
