Blue5ive Motorcraft AZFS22C part # 463 is the copper. If you go in most places asking for SP-463 or 463 plugs they will have no idea what you're talking about. It throws people off when 463 is the only info given them.

Andrews-bad-SE I got my Motorcraft SP-463's... The threaded part seems a little shorter than it should be. Should I be concerned? Or am I being a worry-wart?

Wrong engine bud.
The 104's don't fit a zetec.

Blue5ive Never heard of a loss in mpg when using copper plugs. I didn't see a drop.

iminhell The coppers (SP-463) is a colder plug.

I've no clue on MPG loss or gain.

Andrews-bad-SE Thanks guys! I got a set of Motorcraft SP-463's coming now. Here's a related question... I've heard that fuel economy drops when using a copper plug. But the copper plugs are hotter, resulting in more fuel burn. Why is this? I mean, I'm not really that worried about losing an MPG here or there to make a little power, I was just wondering why that is.

zetecDon Either stick with what the manufactor recommends or going with the Motorcraft or Autolite copper plugs. Other than that, you aren't going to see any significant increase using those plugs.
