Gap them at factory gap of .053".
NGK's are good. For a good cheap plug, cannot beat the Autolites.

Autolites. I'd still buy them if they cost 5x as much as they do.

I've tried too many others to remember.

Plain, cheap Autolites. Dyno proven results and they are only like $1 each.
Don't even get the Platinum ones, just the plain copper ones.

Autolite 25s for a stock 5.0 all the way. Regular version, no platinum, no fancy crap just the cheapest ones.

Autolite Copper plugs

25's for my fox bodies

3094's for the Cobra

dont quote me on the number for the Cobra right now though.

I only fouled out the plugs once in the Cobra but it was my fault.
85 octane + 120 deg weather + stop and go traffic in Vegas + 14 deg advan = fouled plugs

Which are identical to the Autolite versions….as that’s who makes them.

I’ve had great luck with NGK’s….although my application is a tad bit different.

Ha. It's been a while since I bought 'em and I was taking a guess. I was way off I guess.

I just put autolite 25s ($1.64 each) gapped at .054 in my 94 GT last week and they solved my missing problem. I've read that some people have had good luck gapping at .045-.050, but I just stuck with the Ford specs for now. I had NGK UR45s for the last 2 years and ~9000 miles. I don't know what happen to the NGKs because they all visually checked out but for less than $15 I took a chance and just replaced them. I'm going to guess that somehow one of the NGKs grounded out or the insulation cracked and I just couldn't see it. Either way, I searched a while trying to find a good plug, just as your are, and I found that most people leaned toward Autolites 25s in a 5.0 GT. I only have 150 miles on them but no complaints either.

YES, Autolite 764's are for the Cobra's. I'm running Autolite 3924's gapped at .044'' in my 185's.

Do you have GT40 heads or aftermarket?

As mentioned Autolite makes the Motorcraft plug. I always used the Motorcraft plugs(Even in my procharged BB Chevy boat motors). I switched to the Autolites because the coldest Motorcraft gasketed plug was a 32series, Autolite racing plugs go down 3 to 4 ranges from the Ford plug and there racing plugs (AR series) work great and are cheap(heavy body,cut back electrodes). This same conversation is going on in the 5.0/5.8 forum. If you spend a little time on Autolites web site you can find out a ton of info. In a HP application a colder plug is a better plug.

If its a NA car with tappered seat heads go with the Motorcraft AGSF 32C, or Autolites cross referenced on that #. The AR plugs are an impressive plug though, under $4, and easy to get, Summit carries all of them.

Just found out that Autolite 764s are now Autolite 104. Just a number change. That's it.
