Should I be worried?

Cory281 · May 18, 2008

Hey guys, I have a 08 Mustang GT and I've been reading all the nightmare stories of changing spark plugs on these cars. I was hoping mine had the new 1 piece plugs, but it doesn't I really don't want to deal with this problem at all in the future. Should I be worried about this?

I believe that all 08s have the improved plug. But just in case you can take the plugs out and antiseaze them just to be safe...

Hoboattacker · May 18, 2008

you should be safe but like redneck said, use anti-seize just to be safe.

Your '08 should have the new style heads/plugs. Best way to be sure is to pull out one plug following the recommended removal procedure for the old style plugs. Compare your plug to the pictures (new style vs old style) posted on the other thread. If you have the old style, pull them all, put anit-seize on them, reinstall them and you're good to go. If you have the new style, reinstall the one you pulled and count yourself lucky. I pulled all mine (07 GT - old style plugs) yesterday after 7200 miles and they came out no problem at all.

If your build date was on October/2007 or later. You have both the revised heads, and new spark plug design. However if the build date is prior to 9/07. Then you'll still have the previous version.

How can you check the build date?

Out of curiosity...What is Ford's recommended change interval on the plugs?

Look at the sticker in the door.

100,000miles. Which if you wait until then and have the old 07s and older, they will be stuck for sure and break.

whyask · May 19, 2008

yeh most have been chaning at around 15,xxx - 20,xxx.. Just something to think about !

Cory281 · May 20, 2008

Well my build date is 07/07. So looks like I have a project this weekend. I honestly can't figure out how a bunch of car engineers thought this would be a good design with no problems? The guys involved with these spark plugs shouldn't have jobs anymore. Oh well.

Thanks for the help guys.

xtweakerx · May 20, 2008

yeah im thinkin im gonna do this soon but change the plug to champion or w/e..

can anyone take a pic of the location of the plugs on this car

im so use to the damn 302 fox bodies and where the plugs are on that car but its quite different on this i guess w/ having coil packs n such.

anyone wanna point the location out and/or whats involved w/ a short Tech Write-up guide?

And where are u guys buying your champion or auto lite plugs?

thanks

So what happens if one breaks? Do you drill it out or something? If I had it done at the dealer, do they have a special method?

Ford makes an extractor tool that can remove the separated ground shield after the plug breaks. Depending on the severity though, you might have to take that head off. I would recommend anyone with a low mileage old style plug car to take their plugs out and anti-seize them now. An ounce of prevention ......

Cory281 · May 22, 2008

I'm going to go 1 of 2 things this weekend. Either pull out my stock plugs and put antisieze on them or go out and buy the Champion 1 piece plugs, what should I go with?

Thanks.

If you don't have a turbo or supercharger (they need 0 heat range plugs which Champion doesn't make), take out your old plugs and put new one-piece plugs in. I would also anti-seize the new plugs to make them easier to get out next time even though the one-piece design makes them tougher.

dmaxstang · May 22, 2008

Oh Snap!!

Ok, this is the first i've heard of this and i have an 05 GT build date Sept 2004. The car has 55k miles on it and never had the plugs changed, what do you suggest? Tha nks

Power4 · May 22, 2008

I've never heard of this problem before either. What's involved in anti-seizing the plugs? Just removing them and applying some sort of lubricant or something?

Cory281 · May 22, 2008

Yeah, you need to take them out and put anti seize on them so they don't get stuck from all the carbon build up. If they have been in for awhile people say they are really hard to get out without breaking them off in the heads. Search the forum for more info and the TSB to get them out.

Thanks for all the help guys.

Power4 · May 23, 2008

Should I be worried about taking them out on a '07 with almost 30,000 miles? I don't want to try to put anti-seize on them then end up breaking one of the damn things. Could I just have the dealer do it when they service my car next time?

Should I be worried?
