Thread: The best spark plug for a 04 gt ???

I read alot about all these different spark plug's and gaps , but which ones work the best and why would you change the gap from stock specs ????

you stock?

get ac delco, .060 gap.

best plugs are to keep the the ac delco

I gap all my plugs at .050".

Less chance of a misfire that way because I'm lazy.

@fivefingerdeathpunch , yes , bone stock until this tax season , but plan to go with a cam,pcm, headers and cat back.that all I need.

@matt5112 , thats all I've used are NGK , but what is the reason for the different gaps
