I just ran accross a discussion about anti-sieze on the plugs over on the for sale board. I just changed my plugs and didn't use any. Is this a problem or should it be o.k.?

If you didn't overtorque your plugs, and you don't leave them in there for 100,000 miles or more, it shouldn't be a problem. But if you felt like it, you could always take 'em out, put it on, then put 'em back in. The stuff isn't "suggested" by Rover, but it's your truck, you decide.


Best o' luck,

I would use it. I recently bought a BMW, the guy I bought it from spent the big bucks, went all out and put it some Bosch Platinum 4's. I noticed one day that the car's power seemed to be slipping. I pulled to the plugs and to my amazement, he had put the plugs on himself, hand tight, without anti-seize. The plug holes (covered) had actually filled in with motor oil in all but one. I properly put the anti-seize on, and torqued them to the proper setting, and cleaned out the oil. Needless to say it made HUGE difference with the cars performance. When I changed my plugs on the LR I used the anti-seize. I recently pulled a few to see how the plugs where doing, and everything looked great. I'd suggest using it + the lube for the connectors.

Steel fitting in aluminum (heads/block, what have you) = trouble at some point. Anti-seize is easy and cheap - why not use it?

Thanks everyone. I think I'm going to go ahead and pull the plugs and put anti-sieze on. Now, what is this I am reading about the lubricant for the connectors? I've never heard of this either...still learning here.
Would this be applied to the inside of each end of the plug wire to ensure a better contact???

Just regular engine oil on the threads is quite adequate...the real deal is do not overtighten them...!!!!

Yeah - until that engine oil breaks down at 300 deg F and turns into sludge in your plug ports which run at CONSIDERABLY higher than that temp.

This isn't theory - it's from experience with high dollar alloy race blocks and heads.

Again - why do it half-assed when you can get the right thing for the job?

Also - about the lubricant for the spark plug boot - it is a very good idea - except use the right thing - dielectric grease. It will help to seal/waterproof, assist in later disassembly, and prevent any chance of misfire due to bad conenctor to plug connection.
