I'm looking into purchasing these in the next few days and wanted to know if anyone one else has put them in their truck. I have a 04 XLT v6 4.0L SOHC 4x4. I'm only interested in these because they claim to give you more MPG, Torque, and Horsepower. Opinions?? Or what other brands should I purchase. I'm more interested in it giving me more MPG.

did you end up using these and if ? how were they =thanks
Junk. They do nothing. And fords don't like anything other than motorcraft or autolite
Exactly.
Spark plugs are just another link in the chain. You'll never get a "hotter" spark by just changing the plugs. You'd have to upgrade the entire ignition system.
