(im going to try motocraft fine wire ) the gap should be stock(.054) unless you are running 10+ psi. NGK TR6 is what everybody is using I'm in the middle of the project with a V2 sq @ 7 to 9 psi. with cooler on my stock 1997 cobra.....i still do not have it tuned........good luck......
I run the NGK TR-6 as they are a range cooler than stock. Mine were originally set up with a 0.054" gap but I had misfire codes showing up. I closed the gap down to 0.035" and the misfires went away.
