stock plugs, never been changed is gapped at .060 i believe but normally they're between .040 - .060 depending on the specific type of plugs and engine application

it should say on that sticker underneath the hood, i think on the driver's side fender well, but i think cox is right. also, when you buy plugs, they should come pregapped anyway

I've always used NGK TR55's. They already come gapped at .055". I just check em before putting them in.
