Driver spark plugs for C2 BB (recommendations)

[Wayne M.]

Don't want to dirty my 2 NOS boxes of AC_43N's, or even my set of NOS AC_44N's, for that matter. Removed AC_R43XLS's, and they look as though they were a little cold (range) for my style of around-town driving.

I hear that Autolite # 65's are appropriate. I also have a barely used set of Champion R5N5C's. Any non-AC recommendations ?

If it were me, I'd use Champion RN14YC.

I would use the nos plugs, You don't want to risk contaminating your engine with a non original spark.

I wouldn't recommend any "R" plugs, especially if you have repop wires. The 65's are a excellent choice and AC45N's are a good choice. If you have a go fast motor (12.5:1) then I would use Champion N-65Y for iron heads & N-63Y for aluminum heads.
