|Gobliz||EDIT: BEWARE When you go to an auto parts store as I did and tell them SP-463 they may hand you plat tips. They did to me :( Can't afford 12$ right now to replace so... it for now|

|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?|

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.|

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.|
