Thats what I thought.125. That seems so undersized. I just removed them and went to the 140. I havent fired it up yet I am going to put in hotter plugs and increase gap first.I am running the accell coils. I let you know how it runs.Any tips?

Yeah, I recommended the Accell coils to you. How are they doing? I changed my NGK 6s to NGK 5s reg plugs not platinum and I get less carbon. Still using the .035 gap. Of course I do a lot of short trip driving.
