Spark plug OEM FORD or Motorcraft

Motorcraft is all I use , heard to many stories about aftermarket plugs causing misfires

I do run Motorcraft plugs because they seem to crack a little less than the Autolites.

Had to replace the plugs and ignition coils last summer and that fixed it.

anecdotally, my truck was at 226k when i changed the plugs. motor craft plugs coated, no anti seize, torqued tighter than advised. probably 20lb ft. 2 rear plugs were originals. i’m now at 235k and nothing wrong yet.

I’ve found that Motorcraft platinum spark plugs work best in my 1998 Ford Ranger. I tried Bosch plugs and it ran terribly. Nothing but Motorcraft from now on (for Fords).

My 2000 Ford Ranger with a 4-cylinder and manual is just about the simplest vehicle that could exist. SOHC engine, so not much that can go wrong in it. It's very satisfying to work on because you don't experience the shitty feeling of knowing you spent way longer on something than it should have taken.

Stock Ford ones were $9 a piece at my local dealer…

2005 CVPI...180,000 mi....spark plug blown out of head. The Crown Vic was purchased at auction for $4200 a bunch of years ago with 100,000 miles and was very good to us until about a week ago...original engine, suspension parts, transmission and very few repairs.

Iridium plugs suck on fords.

I own one of these, and I couldn't have a lower opinion of Fords engineering (the 2v spits out spark plugs? lets "fix" it on the 3v and make it so they will never come out).
