I'm running .060" with a set of AC Delco plugs which I indexed, but I'm also running a 71,000 volt coil and race module. You can go higher with some of the multiple spark discharge boxes, but I haven't seen anyone go above .060".

You likely wont gain anything using a wider gap.
And it will require an extended gap specific plug. Not the R44TS plugs... And all those extended gap plugs are projected tip plugs,so consider the heat range carefully. And projected tip plugs are not "racing" plugs really,so that's not making a big improvement here either. Like I said,leave the R44TS plugs in there and keep them gapped at .045",JMO. For more specific recommendations we would need a whole lot more in-depth info about this combo. |

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.
