[QUOTE="BuffDigits, post: 1148035, member: 12344"] nothing wrong with motorcraft plugs, I had to just recently throw out my NGK's, went back to platinum motorcraft plugs and things are much better. you generally do not need to replace your plugs, however as you increase boost it is common to have to make the gap smaller (hence make the plug "colder") to reduce spark blowout. you really want to keep the gap as hot as you can so when you run into problems make them a little colder. No reason to, for example, jump to a really cold plug right off the bat. also there isnt anything unsafe about keeping your current plugs. In my case it was safer to stay with them. (mind you my NGK's seemed fine for about a weekk then problems started happening) lots of people change them out without any problems but unless you really really need to dont. in your case you probably wont need to but a tuner (while your car is on a dyno) would be able to tell you more reliably.
