Spark plug gap...

What is the gap supposed to be? I removed mine and they look like they might not all be the same. What problems could that cause and what is an easy way to clean them here at home?

Stock gap is .050

If your not sure they are all gapped the same, why not just go spend $20 and get new ones? If you would rather keep the ones you have, I've heard of people using wire brushes to clean plugs.

Where can you get the ac delco plugs for $20? And they are new, well about 7 months old. Thanks for the replies guys!

Always change your plugs when you have them out.

Always "check" the gaps, even on new plugs to ensure the correct gap. JMHO
