 a little bit of silicone that you put on the ceramic of the plug. For lubrication. Yeah, so it doesn't stick later. And some people just smear it all over the plug, and they'll get it on the metal part of the electrode and everything. I don't like to do that. I like to put it just on the ceramic, and then when you put the plug wire on, it clicks on, because that's where it's meant to be. It's not on the tip, but on the actual ceramic. And the pass on the anti-seize. On the plug itself, correct, yeah. I don't see need for it. I just don't have a problem with it.
