4700 mile and......(re-visited)

[new2BIGPAR]

Well, after having my car for a week for smoking on start up I finally got the call today that it's ready. I tried to tell them on Friday that it was my plugs that were fouled out, but they had to do what Ford was telling them to do, and that was to put some dye in the motor to check for oil leaks. Anyways, they ended up changing the plugs to a colder plug. Is this gonna hamper the performance, HP, or anything else?

Thanks, Corey

The colder plug should actually help your performance a small amount.

If the plugs were fouling, wouldn't you need a hotter plug?

I know of guys using colder plugs when using nitrous, but I wasn't for sure with a S/C'ed car. I'm not so sure if the colder plug is gonna foul out in a few thousand miles or not. If they do, they'll be replaced under warrenty again. The car does feel a bit better with these plugs.
