The geniuses at MSD tell you to go a step colder than what the head manufacturers recommend (so that's the Champion RC9YC5). Some people love Champion, some people hate them... but they seem to do fine for me. |

Either one is fine. I like the Autolites.

The only problem I`ve had with the Autolites is the threads sometimes look like crap . Kinda afraid they might hurt the aluminum head . I just bought some NGK BKR6E plugs that are equivalent to the Autolite 3923 plugs and the threads look a whole lot better . The AR 3923 heat range works ok for me ..... but I suggest you err on the side of caution , or rather colder , than destroy an engine . You can go hotter later if the 3923`s are too cold .... after all , plugs are cheaper than an engine . What you are looking for is a 14mm plug.
