I went scrounging around & through Summit I got a tech support guy, Gary, on a SATURDAY! I'm impressed, that's pretty good customer service on both ends. Anyway the MOTORCRAFT application is ASF-32C-    platinum  w/ .054" gap!

Cool. I'm puting a GT-40 headed 5.0 HO in my T-bird in the spring and I was wondering what plugs to use.
88 Thunderbird LX: 306, Edelbrock Performer heads, Comp 266HR cam, Edelbrock Performer RPM intake, bunch of other stuff.

or when you go to the auto store ask for plugs for 93-95 cobra or 96-97 explorer/moutaner

autolite 3924's

and i would'nt gap them @ .054 on less it's a bone stock SO motor..

for a N/A motor under 10.0to1 gap the plugs @ .044

for a N/A motor with 10.0to1 comp or more .035

for a supercharged motor like mine .035

for a supercharged or turbo motor @ high levels of boost as low as .025 but will take some trial and error for best resolts..
