Ok, I am going to be installing a set of Zex plugs tomorrow, and I need to know if I need to put anti-seize on them... I have searched and read, and mostly I get people who are bitching at each other with yes, no, yes, no, etc etc....

And, if I do need to put it on there, how much? How should I apply it? I changed the plugs in my last car (1998 Honda Accord 2.3l) and I didnt use anti-seize then, but I didnt care nearly as much about that car

And, to tighten them down, I read 15 ft-lbs to torque them to? or 1/4 turn past finger tight? Which is it?

Thanks in advance.

 

a half turn from finger tight.

 

I never put aniti-seize on the plugs when i insall them.I never had a problem with removing them without it.If you have some,you might aswell put some on.When you tighten them down,just snug them.They dont have to be too tight.

 

I use just a dab of anitseize and spred it into the threads carefully with my finger. Do yourself a favor and get yourself a printout of the torque specs or search on here for the full list someone posted, and BUY A IN.LB. TORQUE WRENCH! Everyone please stop guessing on turns and tightness, and torque things to spec so they don't break or strip out! Make sure the car is cold when doing so as well.

 

yup. a dap of anti-sease and torque to spec. Broke a spark plug once in the head (when i was 16) and that sucked. Was lucky to use a reverse bit and got it out..but not cool. Overtightened it.

 

Okay, backyard mechanics say don't use anti-sieze and don't use torque specs.

What does your head tell you?

Ofcourse you use anti-sieze on spark plugs. That's why it exists. And the torque for plugs is 15 ft/lbs.

 

for the75 cents to a dollar, its worth the price to have your plugs come out easier and not worry about them breaking

 

yah i always use antisieze on my spark plugs, its better than having them break trying to get them out.

 

Spark Plug Manufacters say not to use anti seize... they are not back yard mechanics...
Both NGK and Champion ( Federal Mogul ) state this.....

 

Steel threading into aluminum why would you not want to use anti-seize....

 

Who in there right mind would buy a Champion spark plug anyway? Unless its for a lawnmower or something...

 

Chrysler products use Champion.

 

The torque specs , yea I agree with . I dont use anti seize though . When it comes time to take the plugs out again , they thread out ALOT easier without it :shrugs:

 

well, I put them in without anti-seize, and they threaded in fine. It didnt look like the old ones that GM put in had any on them either. From what I understand they seize up up if you leave them in too long, so I'll check them periodically. Also, I read from manufacturers that said not to use anti-seize.

The car idles ALOT smoother now, I mean like to the point where I had a rattle go away... Seems like it runs a little better at higher RPM's as well. All in all a nice little investment I think. Thanks for all the input guys, greatly appriciated!

 

nope dont need. it the plugs wont rust, and its alumminum block threads. but they could get seized on from corosion. but i doubt it there covered over pretty good from the 2.0s or 2.2s the 2.4s have coil packs on top.

all NGK plugs come with a coating from the factory to stop corrosion and seizing... not sure about Bosch or champion or the others...

 

The plug manufactures say dont use it because of 2 reasons...

Alot of people OVER USE it and it gets on the insulator and misfires and it can also actually melt and drip down into the chamber. Also if used the plug torque should be lowered due to the threads are no longer dry (which most torque values are with dry threads).

If you use it just a very small dab is all that is needed. Once you break a plug off in a alum head then you will realize why its used, but I only use it on alum heads as I have it laying around and it sure doesn't hurt anything to use it.

Just flip a coin I say....

 

Yeah, I think I am going to keep an eye on them, pull them and check them at oil changes to check for corrosion, wear, etc etc... I do see your point about people over using it though
