you prolly wont see a huge difference because the plugs are only as good as the wires, coil, and distributor that power them. in order to notice a difference you would have to upgrade all of that and that can be pricey. youre better off just sticking to motorcraft parts or their equvilent

the e3 are the ones that are supposed to provide 3 times the spark because they have 3 electrodes? bull****! electricity takes the path of least resistance, meaning it will only flow through one electrode. power will jump around from electrode to electrode but the benefits are going to be minimal if any. and remember these cannot be properly gapped either

im using them for my 5.0 swap. Normally i would agree with you about "over claiming" but if you saw power block on horsepower tv they did a test and proved they do actually work.

Use a motorcraft or autolite plug. The ranger engines don't run as well with other plugs, they are not the proper heat range normally.

If you saw it on TV, it MUST be true! lol
It is called paid advertising, you can skew anything to show gains if you wanted to.

I got the E3's in my 2.3. Not worth the money. The only thing I notice is that it starts quicker. Not much off the line to begin with but and can chirp the tires now. I had to trim down the #1 spark plug boot for it to reach the spark plug. They are of equal length but they are not at the torso/nut. The torso/nut of the E3's sits higher so its shorter when its in the head. The boot popped off and I was running on three cylinders till I got home from work the day after I put them in.

I believe the idea behind them is that they actually are supposed to be not create 3x the Spark, but rather since they don't have a piece of metal directly above the spark, the explosion can burn more completely because it can go directly upwards instead of wrapping around that metal.

Not sure how much fact there is to that, but they were recently up at my Alma Mater (Michigan Technological University) and I believe that was the story line they gave.

Now as far as what other people said, I'd agree. If your only putting in E3 plugs, your probably not going to see much. I put them in my 99 and it ran just as well as when they weren't in there. Didn't see any gains or losses really. Maybe a slight gain if I remember right, but that was probably more due to getting new plugs after 100k.

If your going to do the whole system, I'd probably rock them. They seem to be much more based in fact that a lot of car companies and the fact they are willing to go to scientific schools like my college and try and back up there claims makes me think they at least partially know what they are talking about.

A quick article for your reference.
