What plugs for upper / lower / port combo??

[JA$ON]

I am running good ol TR-6's with the port and upper now (14 PSI). Car is going in for addition of 2lb lower, do I need to run a colder plug for 2 more PSI, or can I just close the gaps down a bit on my TR-6's? My car runs great with them and I really dont want to mess with plugs if I dont have to, but I will gap em down. Car pulls great all the way up in the RPM range now. Any thoughts??

The TR6's should work fine with that combo with a .028 - .032 gap, but if you want another step colder I have some BR7-EFS's I'll sell ya.

Not to hijack, but what about his same combo and adding some spray to it? Will the br7efs work?

IMO, yes.

br7ef has the grooved electrode, br7efs does not.

Car has been running good, just a few creaks and groans here and there. Unfortunately I think that was the last day for DA's in the low 100's for a while, so it's doubtful I'll be going faster anytime soon.
