I've had a 2010 Gt for alost a year now and it has about 13k miles on it. I was wondering if replacing the spark plugs would be a good idea, i've heard of some power gains and better m.p.g. that comes with it as well. Any light that can be shined on this subject would b great help thank you. Also i DO NOT want it to void the warranty
If I was looking for power gains I definitely would not count on spark plugs to give it to me. If you really want to see some power gains start with a CAI and tuner.
haha yea i know that...lol...i forgot to mention i have a intake, tuner, a cat-back exhaust. I was just wondering if they do actually make a difference because i have heard that they do. I'm just trying to find things that wont void my warranty and the exhaust is a roush that was installed by a roush dealership so it wont, the intake wont either, an the tuner will be easy to rever bak to the stock settings. Once my warranty my co-worker and I are gonna make some custom parts(headers, X-pipe, better induction tube, etc.)
The only reason that I would switch the spark plugs at 13k is to replace them with a one piece design before the stock two piece ones get baked in there too much.

Are you sure you have the 2 piece plugs? If you do, then I would replace them with 1 piece plugs. Sorry.
