Glad to here you like your plugs. I wonder how much boost you can run on those before blowing out the spark. I would love to try these, being a spark plug nut. But since Brisk warned against using these with an undisclosed amount of boost, it would be a shame to buy, try and it fail. I see you have basic mods. Can you do a scan and see how your engine does? Please please.

What plugs did you have, mileage and condition?
