Most "better" plugs come pre gapped, you're not to touch the business end of the plug, skin oils contaminate it. You can call any auto parts store and get the gap, and GM dealer will give the gap, you could check the application charts for the spark plug and get the gap, you could check the sticker under the hood, they used to give the gap. You could buy a Haynes, you'll find the gap in there. You could check the Internet for the gap.
