Thanks for all the great threads you've taken time to post over the years - amazingly helpful!!
If you don't change the spark plug gap after installing this mod, what are the drawbacks or how much of the gain are you losing? I have the standard 3 prong plugs and I'm not familiar enough with re-gapping, the re-gapping tools I recall seeing I don't think would fit under the electrode because the other 2 prongs would block the tool? A few pics of the tool on an old spark plug would likely set me straight if you can take some (yes, pretty rookie question)!
Also, while this isn't a top concern for those buying this, what are your insights on whether this mod would actually help improve gas mileage (all else equal that is, since this might alter driving habits with the more powerful throttle response!) due to more complete burn of the gas in the cylinder with the more powerful spark and resulting combustion.
Similarly, it sounds like this should actually help emissions as well, just as you mention the post-facelift versions had this for improved emissions.
Thanks again for all the great threads over the years!
