I am amazed at how many people do not have the owner's manual that came with your car. The answer to lots of these questions can be found just by reading the owner's manual, or in your case by also looking under the hood on a placard, where the gap is listed. If you have one, read it. If not, then get one. Sources for an owner's manual are, Dealer, E-Bay, Salvage Yard, and many on-line web sites. One site is http://www.samarins.com/maintenance/manual.html Check the decal on the inside of the engine compartment. It provides the suggested gap for your plugs and provides additional information about the emission system as well.
