Hey guys, I just started using Autolite 4164 plugs in my 07 117 ci. They seem to run real nice and are every bit as good as the Champion"s I was using. Any one else have any experience with these autolite's? Maybe a better suggestion as to an even better plug?

Thanks Sul. I can always count on you for great advice as well as so many other brothers here. Next change will be the NGK dcpr7e's. They will be alright with the stock 9.5 to 1 comp? Should I regap them to .036?
