hot rod tv (or something like that) did a dyno test and got 10 extra hp from them, or was it 5?, cant remember.  make sure you measure overall length of electrode as i have heard some of those plugs have kissed pistons.

horsepower tv tested em out on the dyno and broke it down by HP per amount of fuel used. They got more power out of less fuel. Also did a test with the plugs in a visible spark chamber and said the E3 had the most visiually impressive spark.

I run E3s in my daily driver and in small engines (pressure washer, mower, generator) and they diffently made the mileage go up in the driver and the small engines run smoother, as mentioned earlier check the electrode length against the plugs you pull out to make sure you don't have clearance issues.

I have been using them for the last 3 months in my 440, big difference in power and fuel economy.  No clearance issues with my CC 516 heads

Please elaborate on how you determined power difference!

good point rex, but for all of those that do not know, make sure you understand that not everyone runs the same combination and piston height's are different no matter what heads you may use.

I hadn't heard anything about these plugs myself, but I figured hey... somebody has to try them, so I have put them in my new 6-pack build. The engine was just fired up for the first time the other day, for the cam break-in etc., so I can't really say too much at this point... other than the fact that it runs great so far. We will be putting a load on the Dyno when I get back to CT sometime next week. I personally like the design of the plug myself... I think they cost to much, but obviously I have faith in the fact that they will perform, or I wouldn't have wasted money on them in the first place.
So... did I waste money... I guess we will see soon enough. Hey, if nothing else, they are backed by a decent warranty.

i run these in my Ram (5.9 mag). biggest thing i noticed is there is no more "pinging" when i run regular fuel. (tested it..) out of habit though i still just use mid-grade on her though. the truck gets such bad mileage, i really didn't notice an improvement on that.
