According to this link the OEM plug thread size is 17mm.

Sorry, here is a better link with more info on the Specs tab. According to this, the thread size is 14mm and the thread pitch is 1.25 .Quote:

Perhaps someone can confirm this by actual measurements. I don't have one nearby.
Yes it is.. M14x1. 25
Thank you! I ordered a tap for it and now will just have to get the courage to do it. Thanks again.
Did you cross thread the spark plug?
Is it going to hold?
If the threads are damaged typically you do not try to "repair" them with a tap. The preferred method is to get a Heli-Coil kit or one like it. It comes with a drill, a tap, an insert, and a tool to install the insert. You drill the threads out, retap and install the insert. Makes it better than new. Most auto stores will have a kit or can get you one quickly. To prevent this from happening most mechanics use a drop of Never Seize when they install new plugs.
