hi, my first post. I purchased some new spark plugs I'd been hearing about, guess what! couldn't find any old plugs. now I know I don't have a diesel, couldn't see anything. what I have is a 2007 gmc caynon. 2.9 lt. automatic. raised vec up, I crawled underneath. nothing. where do you suppose they put those plugs. called the dealer, bring them in & we'll install them, but cant give out that info! anyone got any ideas. thanks. reid

they are threaded into the cylinder heads. follow the spark plug wires.

thanks for the quick reply, there are no wires showing, no distributer cap, no coil.

This probably has COP ignition...
(C)oil (O)ver (P)lug
Each cylinder has its own coil.
Remove each coil and the plug should be underneath

What kind of plug did you buy? If it is one of the "gimmick" plugs, return them and get your money back. I am a firm believer in OEM plugs.

?? Why are you replacing this type of plugs in a one year old vehicle? Don't those claim they are good for 100k from new?

Stay with AC Delco. In about 10k miles you will see why.

Not a snowballs chance! Hit back when you check mpg again. Do you think for a nano second that a major car company wouldn't be doing that if that was even helpful let alone that kind on increase?
