Lynno Posted November 13, 2014 Report Share Posted November 13, 2014 I have the original two piece plugs installed by factory in my 2007 and now I want to change them. I have 13,000 on my Shelby GT now. I have read about the trouble with these plugs and want to get them out before they break apart when removed. What is the best one piece replacement plug to install NGK, Champion? Link to comment Share on other sites More sharing options...
ilmor Posted November 13, 2014 Report Share Posted November 13, 2014 Yeah, I should probably do the same.... Link to comment Share on other sites More sharing options...
07SGTC Posted November 14, 2014 Report Share Posted November 14, 2014 I would like some more info regarding what plugs to install and any pitfalls or suggestions when changing out the plugs as well. Link to comment Share on other sites More sharing options...
MyBlueHeaven Posted November 14, 2014 Report Share Posted November 14, 2014 I just did my plugs last night since I installed the KB this past weekend, my car has 47,000 and some change on the odom. I had ZERO issues removing the plugs, and let me tell you of the whole entire supercharger install this to me was the scariest part, because of the horror stories that I've read about from others that have broken them. I did what others have posted, cracked them all about 1/4 - 1/2 turn and then sprayed some PB into each plug. After letting it sit for about an hour I then proceeded to remove them all. Most came out very easy, all but one as a matter of fact, almost could remove them without the ratchet by hand, I had one that presented a little resistance but I went slow and back and forth a few turns and it came right out. Ther was very little carbon build up on that one so it wasn't in jeopordy of breaking in the head, it was just a little tighter. For you guys with the very low miles on your car there will be almost NO carbon build up from use, and thats what locks the tips into the head and causes them to break. I had to use a lower heat range plug for the SC, so I'm unable to give any insight for the best replacement, but I wanted to post to let you all know it's not going to be as bad as you think or have heard with your low mile cars. Hope this eases the anxiety a little. Jeff Link to comment Share on other sites More sharing options...
Bill_T Posted November 14, 2014 Report Share Posted November 14, 2014 Thinking of changing mine also. Since it's now in the garage for Winter. Hopefully someone will recommend the best plugs. Link to comment Share on other sites More sharing options...
GTH391 Posted November 14, 2014 Report Share Posted November 14, 2014 I changed mine with the one piece Champion 7989. They cost a crap load more but I am not worried about the breakage issue. I also used anti-seize in the "neck" that extends down into the head. Keep any anti-seize off the electrode. Just smear it lightly on the extension. Good luck and take your time!

I did the same thing when I installed the new ones. Anti-seize on the threads and all the way down the neck, stopped short of the tip and strap area like you mentioned. The FRPP plugs I used have the strap like the orignals. Link to comment Share on other sites More sharing options...
old man Posted November 15, 2014 Report Share Posted November 15, 2014 I changed my plugs on my 07 at 32 thousand miles with no problem using the process mentioned above. I went back with the same plug. My son tried to change his on his 05 Ford truck at 110 thousand and broke every one. A tow and 550 dollars at Ford fixed that one. I also purchased my self a plug removal kit for about $50,00, and hope I never have to use it Don"t be afraid if low miles and just do it.

07SGT2899 Posted November 15, 2014 Report Share Posted November 15, 2014 I did mine at 10k and they practically unscrewed themselves. I replaced with oem plugs and a little anti seize Link to comment Share on other sites More sharing options...
Lynno Posted November 22, 2014 Author Report Share Posted November 22, 2014 I did the job today and the plugs were not bad. I did go with the described info of how to remove from Ford. The plugs came right out. At this time I cleaned all plugs and added the anti-seize to the ground electrode cover and threads. I reinstalled all plugs. Soon I will replace with one piece. My suggestion to all is get the job done a soon as you can. It's all about keeping these cars running at peek power. Link to comment Share on other sites More sharing options...
