Thoughts on use of antiseize on spark plugs?

about to pull RunRun's plugs and read them, i see a lot of advice to use anti seize, is it a factory practice?

any opinions, any problems from using or not using?

 

I live in New England, I use that sh!t on everything except lug nuts.

A dab or dielectric grease on plug boots as well.

 

Always on spark plugs. Don't need to use a lot.

 

Installing plugs for over 50 yrs, never used it on any plug installation. Just did plugs on my 4Runner @ 100k, used oem Toyota plugs no issues with removal of original plugs. Reinstalled new without any anti seize...just me

 

Factory doesn't use it, I don't use it. Have replaced dozens of plugs for my cars and other folks.

 

Apparently some Honda engines have factory service instructions to use anti-seize. I would never use it unless the manufacturer uses it.

 

I've never used antiseize on the plugs of any vehicle I owned. I used to use the "tighten till it touches, then 1/4 turn more" method, until I found a torque spec in the FSM by accident. I was surprized at how close to "waaaaay overtight" that 1/4 turn put them.
I've got a thread-chaser for spark plug threads too. Only NEEDED to use it a couple times, but I was real glad I had it!
Now, I only put antisieze where the FSM specifies to, and threadlock where the FSM specifies too. I check for torque specs more carefully, as well.

BTW: I use the silicon dielectric grease on every electrical connection I put together. EVERY electric connection. The plug wires (both ends), any battery connection, both positive and negative, everything. It's made a huge difference in the occurance of corrosion, intermittent problems, everything.

Have fun!

THANKS EVERYONE. I have also never put anti seize on plugs. I think I won't start now. I use it on the shackles on my anchor gear.

I only have three out, but they are the wrong plugs for this engine. Putting Denso double ground plugs in. I go pull the others and see what got put in there. going out the put it back together.

Thanks to everyone who chipped in.

Almost forgot, I used to use vaseline for dielectric in Alaska for electronics and antenna gear. works perfect if you don't have the real thing. this time I have the real thing, thanks for the reminder to use it!

 

I’m almost 60, and have worked on cars since I was about 15. Never once used it. To each his own though.

 

almost 60 was good, as I recall. I like anti seize a lot when I'm welding pipe fittings through bulkheads. the plugs were all wrong for the engine, but they seemed to be getting good mixture.

thanks again and good night

 

I never ever have...... OEM never does, why would you.

 

If 1/2 the plugs are the wrong ones, I'd wager the rest are, as well. I'd check the wires, distributor cap/rotor, everything. Easy thing to do, easy to fix, if they're wrong.
These trucks seem to run much better with OEM parts in them. I've put after-market plugs, wires, and so forth, in my 87 4Runner, before I sold it, and my Hilux. I've always noticed that OEM parts give me more power, fuel economy, etc. ONLY exception was that the Bosch Platinum +4 plugs I put into the hilux lasted 120,000 miles. Pretty good! When I finally had to finally replace them, I went back to OEM, though.
NGK has iridium to fit these vehicles. I'd use those, and will come the time to replace the plugs in my vehicles.

Have fun!
