Try searching for the recommended gap according to the plug manufacturer. Know the part number, plug type and/or heat range.

Be aware that sometimes the engine manufacturer will recommend a different gap, especially if the OEM plug is discontinued, superseded, or currently made of unobtainium.
Nowadays spark plugs are usually good for about 100,000 miles. As plugs wear, the gap generally increases. So, if you get several different answers, its usually safe to go with the middle one. Unless you are having drivability issues or getting a check engine light, chances are you'll be fine.
