Have used one in a homelite trimmer that made a noticeable difference. Basically I can trim the majority of my yard without using the throttle(homelite's are direct drive,no clutch). I am going to throw one in my M-Series 5hp two stroke as I have fouled the champion plug. Will see if I notice any difference, right now the M-series is not running very well, I am pretty sure that is due to the plug. Basically I was concerned that the injection might have a air bubble after I removed the line and turned the motor trying to figure out why there was no spark. So I added oil to tank so it was getting more than enough oil.

I find all a spark plug has to do is spark and to be in the right heat range. Its just a yearly tune up, new filters and spark plug very cheap insurance.

I'm on board with that! The engineers and manufacturers of these engines spend a ton of money on design. They also spend a ton of cash on things like manuals. Manuals that provide specs and part numbers. If the book says a Champion J19LM, then that is what it gets. If it says an NGK plug then the same is true. They design these thinking "what will keep the end user from calling us and complaining?" In my opinion, if a manufacturer spends the money to come up with things like- stickers that provide very specific starting instructions, then there is probably a reason.
As far as the E3 plugs. I think they are 99% marketing. Something new, new design, flash name- quick sell as many as you can for $6-$7-$8 a piece before people figure out that they are just a spark plug. I think there will need to be some sort of mind blowing revolutionary design change in spark plus before a new company will be able to become a contender in the market.
