If you put them in, out of the box, there is no "wrong gap." They are preset at the factory. If you stick a gap gauge in them, you'll destroy the platinum coating. Your car will start okay, run okay for awhile, then start to break down and miss and choke out at stop lights, or whenever you stop, from flooding, because all the gas isn't being burned.
But if you replace them with certain spark plugs which are designed to be used in multiple cars, spark gaps may vary. Be cautious about sticking any old spark plugs without checking the box and the required gap needed for your vehicle. However, if the box says it is preset, you should not change it from it's preset, unless it specifically says you may need to.
If the gap is too small, it can cause knocking, in which the fuel burns too hot making it explode rather than combust. If the gap is too large, your fuel won't burn correctly. Be especially leery of using a custom mechanic who says that using a smaller gap is better because it will burn off all the crud that can build up on spark plugs. Stick with manufacturer specifications, and take it to a certified mechanic or another shop if it is ever brought up.
