I tried searching but I couldn't find anything about this being covered previously. So here goes! :D I have an '08 with the flex fuel 4.7 engine. I'm thinking that it's time for a tune up. It has 166,000+ miles on it now, and God only knows when or if anythin's ever been done to it. So, i'm looking for info about what plugs work best and if there's an aftermarket coil available. I'd like to upgrade slightly if I'm buying parts anyway. Unless of course there's no upgrade over stock, or if it's worth the extra effort.

Thanks everyone! :cool: :D
