Spark Plugs and Anti-Seize
 

Is it okay to use anti-seize with sparkplugs?

Or, is the metallic goodness going to work its way into my engine?

Always use an anti-seize compound on your plugs. It doesn't take a whole lot. Just enough to coat the threads. Wipe off any excess before insertion.

I was told by a Master tech not to use anti seize on NGK plugs.

iI was working on Mazdas before that master tech was born and I say use anti-seize.
Nothing like getting a sparkplug stuck in a rotor housing.

Use it...it won't hurt anything......you don't need to goop it on though. A little bit goes a long way. Doesn't hurt to put it on a lot of other bolts that you remove either...makes life simpler down the road

always have, always will

I did for both my car and my father s mini van.

the tech who did my plugs 13 ~ k miles ago didnt apply shit, and it was really a bitch for me to try to get it off .... I was actually afraid that I might break something then my engine will fuck .... lucky nothing happen.

Highly recommended. The only problem would be if you gooped on so much that it got onto the center insulator. Use a small amount; about the size of a small pea, and work it into the sparkplug threads. I usually leave the last couple of threads dry at the end of the plug to make sure I'm keeping the stuff clear of the business end.

I learned my lesson on my Miata when I got a plug stuck in the #1 cylinder. I accumulated about 50,000 miles while thinking about what I wanted to do about it. In the end I sold the car :yelrotflm Anti-seize from now on.

(I did warn the buyer though.)

The other useful salve for sparkplugs is dialectric grease. Apply between the outside insulator and the ignition wire boot. Helps seal against moisture and aids in removal.
