E3 Spark Plugs?

[Tim Mason]

Has anyone used the E3 Diamond Fire spark plugs? Are they worth the investment?

Use Autolite or Motorcraft OEM plugs. There have been too many problems with people trying to use other types.

Agree with Mark K. Why change what works and is proven? Too much hype regarding aftermarket spark plugs. Consensus says OEM for the next 100K. If it aint broke ....

One thing to remember. Drag racers in stock modified division. They use standard plugs in the heat range nesecasry for there motors. That tells me that my street motor will do just fine on the plugs that came in it.

I thought the general disscussion was to change the stock ones over to Champions. As they are supposed to be a "one piece" plug? :unsure:

That is for a V8 Trac.

No AC Delco is a GM plug. Champion is Chrysler

Split Fire plugs did "better" than that on the dyno, then real tests were done and they were junk. I suspect the E3's will prove to be the same.
