Gap for spark plug
Hi guys, I am currently running a Vortech with NGK TR6 plugs. I am thinking about replacing them since I have over 6K since the supercharger installation. The plugs are pretty cheap to replace however since I did not do the installation, I am just wondering what is the correct gap for the plugs? I think they come from the factory at .038 but I have heard that they should be gaped any where from .030-.035.
So for the more experience guys out there, what do you recommend? Thanks

I'd say there are good for a while yet. I have MSD wire's and installed
the tr-6 right out of the box. They are pre-gapped at .039.
I check them and put them in. Stock wires I would gap to .035.

Thanks, I will gap them at .035. I just figure at less than $20 it doesn't hurt to change them.
