AC Delco 61-402 with a 0.035 inch gap.
Haven't seen any test results which show there is a better choice.

I plan to change them every few years.
This is in contrast to new cars with platinum plugs and their 100,000 miles change interval.

What Plug are the NOS guys running? I'm thinking of going to the colder NGK TR6. Anybody use those, does the car suffer N/A when the NOS is off?

AC/Delco (dbl platinum) and still look great after 10yrs.
I pull one every oil change to take a peak.

Can't believe that no one is running the Accel Silver Tip, bargain priced at $72 EACH!
