I have a 94 f150 4wd I just replaced the spark plug wires yesterday and today I'm changing the actual plugs. If anybody knows the proper gap for them please let me know. The truck started missing so this is where I'm starting.

 

It's on the decal under the hood.

 

Not much help if the decal is missing..I don't know. My decal is missing.

 

.055 would work.

 

I have a 4wd 94 and mines .055 gap so I guess it's probably the same

 

Well mine says .044 so .

 

My 89 was .044 I think

 

Yea, mine's an '87. He didn't specify engine size either which might matter. At least he gave the year.

 

Probably the 87-91 302 is .044 and the 92-96 302 is .055 if you have the 351 or 300 I'm not for sure about that. I'd say that they switched it in 92 when they changed the truck a little bit but not completely sure

 

I have the 4.9.
