E3 spark plugs

Anyone try the E3 diamond fire spark plugs in a boat? All the car shows go on and on about them. Of course that is all about advertising dollars. Seems like one of them ran a dyno test and got good results. I have been using AC Rapid fire #1's with .050 gap with the DUI ignition. The E3 plugs are pre gapped / non adjustable.

Don't believe the hype

Just go get some Autolite or AC delco's. Don't waste the money. They aren't running gimmick plugs in Nascar or NHRA why should you?

I'm not one to fall for the smoke and mirrors show. Just thought this would be a good topic to throw out there. If it gained 1/2 mph that would be pretty cheap HP. I have never used the cheaper plugs, they are about the same price as the Rapid Fire plugs.
