I believe the 9ECS is what is recommended. The 8 series is hotter than the 9 but hotter is not always better!

says you

seriously you can use an 8 in place of a 9 if you have to in a pinch, but on a stock motor its best to stick with the 9 IMO, if you mod it up I would run an 8 if you are on race gas. I cut and index my plugs to help with better flame kernel exposure as well.
