I'm just about to change my spark plugs. I notice they are pretty tight. I read a report a while back on the danger of breaking plugs in aluminum heads. I'd hate to do that.

Anybody had any problems in this area?

 

Shouldn't be a problem if they were the plugs put in by the factory. But, if someone had installed the plugs without using antiseaze.. You may have a problem. Just make sure you get the correct sparkplug socket and a good socket extension with a good rachet. It should break free.

 

and don't forget to put antiseize on the threads of the new spark plugs. A couple of bucks of insurance and well worth the money when you have to change them the next time.

 

Really dumb question, but what is antiseize called? I went to Autozone looking for some and I was pointed to the isle that has all types of high temp grease, but nothign that said "anti-seize"

 

Anti sieze is called antisieze. You can either buy the small packets for a buck, or they have tubes of it usually near the liquid gasket and all that for about 1.99

 

This is the one I got, click on Anti Seize for a pic of it (the last one on this page) http://fsjeep.homestead.com/TFI_Upgade.html

 

unfortunately it also might be near the 'Loctite' display. Just make sure and grab the right tube or it could get reeeeeaally ugly.
