Autolite or Motorcraft (autolite makes the motorcraft plugs)

I just changed out mine yesterday. Put in some Motorcraft pieces gapped at .050"

Autolite. To be so cheap, their plugs run better than any other plugs I've seen. I'd stick with the 25s at .050"

i wouldnt be changing them but i recently had the head off and i laid the plugs down all together and one magicly came up missing they was in the car when i bought it and that was 03-03-05. so im just going to change em. just wanted some opinions on what people think. i'll be stick with the autolites

what are you doing with the heads off, bad gasket or upgrade ect....

 

[1SLO306]

i had signs of a blown head gasket and when i pulled them off both gaskets was good. it turned out it was leaking coolant and loosing power from the passenger side intake to head gasket which was also causing a power loss oh well i didnt find out my engine is a 306 because of this

EDIT: did find out it was a 306
