Never seize Yes????? Or Never on your Spark Plugs

So how many times is a little dab too much? Thats kind of where I am headed. If a guy is pulling plugs and checking all of the time. I'm pretty sure anti sieze aint gonna guarentee anything either. I'll use it myself. I just don't want to suggest it if the manufacture says no.
Cadmium plating has been used on old tools and cheap tools for a long time. Good tools and expensive tools use an industrial chrome plating. You know why? Because cadmium rusts. Lots of nuts and bolts at the hardware store are cadmium and zinc plated and sometimes a combination. They rust. It takes a bit, but why take chances?
I kinda keep track of it. If I pull them 3-4 times I put a dab on them. Some guys slather that stuff on there like they are buttering bread. That’s way too much. I put a strip down one side, a narrow, light strip and touch it up every 3-4 pulls.
Thats on the dyno. If I am dealing with an engine that goes 500 miles before someone looks at a plug I use it every time they come out.
I put a ring of anti seize down in the threads and all the way around with my finger. JUST enough to go around the plug threads. I mean really, if you caint figure that out, take up stamp collecting.
I'd think one time would be enough for many changes. But Hey, I'm just another bodyman. RRR is on a roll.

Usually Thats the case. I see every 3-4 times I pull them on the dyno they look pretty dry so I touch them up.
RRR is always on a roll.
What about the head itself? I'ts gotta be building up and cooking in there.
Once you pull the threads you'll wish you used it, a little dab goes a long way.
NGK is giving bad advice, I'd be willing to bet they won't pay for pulled threads from following such bad advice, as I'm sure there are many out there.

I keep an eye on that too. I don’t know where it goes when it’s gone but they are getting dry to.
Come to think of it the more heat load the plug is rejecting the less anti seize on see on the thread. I haven’t really thought about that.
I need to think on it and call my mentor.
It's gotta be playing with heat for sure.
It would be hilarious if it turned out that Brylcreem worked great for this purpose.........
You guys need to get with the game. Olive oil and rosemarry extract. Wait, what were we talking about?
Then the spark plugs would grow hair lol.
I've also used Permatex ceramic brake grease. It's good from -40F to 3000F.
Dissimilar metals
Yes Yes Yes !!!!
Yes Yes Yes !!!!
That certainly is an issue. Hence the plating.
Yes, use anti seize. The 'so called' misfiring I presume would be that a poor ground might be created because there is a ' film' on the threads. The plug will either have a conical seat or a washer.....& both/either will ground the plug body.
I am a Design Engineer. If you do not use anti-seize you are asking for trouble, especially on aluminum heads. It seals out moisture that causes corrosion. Aluminum oxide grows even more that iron oxide (rust) and will absolutely lock parts together. Auto manufacturers say to use it on aluminum heads. I use it on everything including lug nuts. I designed under sea equipment. Corrosion and material selection was a very big part of the job.

I get it, you tell people to use 1 of something, and some mouth breather uses three.
Ngk said zero, so I use a tiny dab (which is still enough to cover Belgium in the stuff). If ngk said to use anti seize, some dill hole somewhere is going to hydrolock a cylinder on it.
I design stainless steel food equipment. What's more sanitary? A little bit of silver paste, or grinding dust from cutting seized fasteners?
Also, FWIW, I put a small dab of dielectric grease on the insides only of the plug wire boots. That way, the boots won't stick to the plugs. Don't put too much, because dielectric grease might interfere with the fire to the plug, since it is a very poor conductor.
10-4 on just a small amount...on the threads. The Lone Star state is 268,000 square miles and one 8 ounce can could cover the whole state.
RT ----your a bad dog ... bad dog ... down ... down LOL I'm still laughing
TT I agree with you guys.... I dont think there are miss fires etc... All of us has called technical assistance and wondered about
some of the answers we get.... All great info ..... in super heated applications in the refining world we even used the cheap dollar store
Phillips milk of magnesia on the threads of anything that was going to be subject to high heat super heated instrument probes, Thermocouples etc... applications
which would back out without thread damage. Some people will not believe it but its true .....

I completely agree with this. The brush that comes in the little jar or tub of antiseize will hold enough to cover an entire garage. I have seen people glob it on a spark plug with that brush and leave a large amount on the porcelain, ground strap, and center electrode. I make the assumption that NGK is doing the right thing in saying do not use it so they can keep this from happening and possibly causing the misfires they mention. Then, anyone that knows what they are doing will still go ahead and use a tiny bit on their spark plug threads to prevent galling.
