Sorry about that 12ounce....my error.
DRW,
"Replacements from Ford are double platinum and cost more than the factory plugs but can be installed in any location".
I think I see what your saying now. The above quote was sent me down the wrong track. I read that as..... replacements from Ford equals factory plugs. The stock plugs I pulled out were Motorcraft Platinum.
So I should be good to go with the Autolite Platinums I installed.
BTW....the P0175 light has not come back (yet!)
Thanks....John
