I love reading ads for the various and sundry "better mousetrap" products out there. Throw in some big scientific sounding words (even though many of them have nothing to do with combustion in an internal combustion engine), and we're supposed to be so impressed we just rush right out to hand them some money.
One thing they did get right, it takes less energy to create a spark from one sharp edge to another. So if you have a marginal ignition system with a coil that barely fires the stock plugs, this could help reduce misfires. Thus the real intended use for these plugs, lawnmowers and similar products. That is what they were marketed for initially, not auto's or motorcycles that have high output ignition systems. And btw, once those sharp edges erode, which they all do eventually, you are right back to square one. I didn't see anything about using platinum or iridium to reduce that erosion.
The only thing a spark plug does is to initiate the fuel burn. Once the mixture is ignited, all the BS in the various ads for various types of plugs is just that, BS. Once the E3 proves to be nothing special, try the PulseStar. Really impressive ads, once again throwing around scientific terms that don't apply, but at around $20-$25 versus only $6 for the E3 you just know they have to be a whole lot better.

Oh, btw, you probably will notice a slight difference immediately after replacing old plugs with the new E3. Of course, you will also notice a difference when replacing an old plug with a brand new version of the same plug. Let us know how you're doing when you hit the 100,000 mile mark they mention in the ad.
