I'm about to change my spark plugs on my 323. I'm fairly handy as i've successfully done a couple diy jobs under the hood (valve cover gasket, ignition coils) so i'm not too worried about my mechanical abilities. My only question is whether I should use anti seize compound or not. I've done some reading here on the forums and elsewhere through google and some people say it's absolutely necessary while others say it isn't. What's the deal. Should I or shouldn't I?
