amc49 I agree, E3 plugs suck. They last because they have multiple firing surfaces, good thing too because they don't even use a precious metal tip like platinum or iridium. In other words, you paid for that awesome marketing program (dig that fancy airbrush work of plug impossibly firing off like a nuclear weapon!!) rather than for better product. An oldschool '50s and '60s plug with a fancy looking electrode, great job there, plug worth maybe $2. They can't be re-gapped later either if you want. At least you could on Splitfires, another gimmick plug using same worn out idea. E3s actually shield the flame from spreading as fast, you either get that or you don't. Add to that the very limited applications with no real heat range choices and you got a garbage gimmick plug. I took back plenty of them while working at the store, on some applications they wouldn't even run correctly to make for misfire issues in engines that proceeded to run perfect again when old plugs put back in.

Pretty funny that someone thinks the engine is smart enough to know whether it has a import or domestic plug in it. If you have proper physical application, tip configuration, and heat range you are pretty much there regardless of what you use, better to use precious metal plugs. I see no problems with the Motorcraft plug mentioned (and Tom would certainly know his stuff!), always best to run same brand plug as the motor as the heat range will be more accurate that way. When you pick another brand plug they often sub a plug that may be in between heat ranges you need and that's not the best part there..............

Also, anyone changing iridium plugs at 10K ain't got his head screwed on right, the plugs are 100,000 mile plugs. Platinum are 50,000, why would you be willing to change them every 10,000 miles? Those days are gone bucko, you're burning money.

Eduktion Thank Tom for that ^^^

1turbofocus Hands down I would go with the SP463 coppers Motocrafts

E3 just have not shown to do what they claim , they last a long time but not good when it comes to performance

Eduktion Hey, Guys just had a chat with a tech he said that he doesnt recomend Using import plugs on domestic cars, he said it wont improve performance, Idk about the gas mileage, i heard NGK Iridiums are great, BTW go to RockAuto i bought a set of 4 for $24 and the wires for $17 way plus shipping it was about $40 not bad at all, anyone else verify this?

2007wagon Not sure if the plugs are different in a 2000 or not but when I replaced my plugs in my 2007 I went to Ford and they sold me the Iridium plugs ($65.00Cdn for 4 plugs). I was shocked at the price but both the guy at the parts counter and several other people I knew said to be cautious using other brands and I figured if the first set lasted 5 years so I used the Iridium plugs and so far so good.

DarwinSays if you don't mind changing every 10k and additionally don't mind spending more $$ over the course, then the coppers will get you a little better performance.
I've noticed slightly better torque when using them, but that could just be in my motor, how I had them gapped, etc..

for low maintenance and longer durability, E3's are a good choice.

I also noted recently that Ford has once again changed the part/number for the spark plugs on my SVT, not sure if the regular zetecs use the same ones - can't imagine why not.

freemind I could not agree more on the E3 plugs. I've been running them for 3 years and they have been great.
