I use the regular 3924's. The AR's just have the ground strap cut back over the center of the electrode.

The AR series plugs have the cut ground as mentioned and a nickel coating on the shell that looks nicer and possibly reduces exterior rust on the shell. Functionally, they are the same. If you have some fouling issues, you could try a 3925 or 3926 which are 1 and 2 steps hotter.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
