The multi point plugs started out in mass with the Split Fire many years ago. They were very sought after, and logically it always sounded like they would work great. I have tried many of them from the Split Fire to the E3, and none ever worked as good as stock. In fact I ran the newer E3 in a car for a month, pulled them out and tossed them in the trash. I have never seen anyone really get measurable gains AND sustained performance from any multi point plugs.
The best really do seem to be the Delcos or the NGK IMHO.
