I am about to order a few things from rockymountainatv.com and I was going to throw in a low-profile spark plug wrench so I can do some plug chops without too much hassle. The question I have for you guys is what is the size of the spark plug wrench. I see them available in 18mm, 14mm and and english measurement that I can't remember right now.

I know I can measure this myself, but I am not near my bike right now, and I am sure that someone knows this off the top of their head.

Thanks,
Chris
