It’s not new. Those plugs have been out for years. The REM plugs are designed for engines that the manufacturers want to go 100k miles before they need to be changed.
They can lose power, especially if the ignition is under powered. What the OP has and is doing is perfectly fine.
It’s dumb to use those plugs if you can get to them. It’s not a performance upgrade.
Years? How bout decades? Especially Platinums. When you said no new technology, I immediately knew you meant the likes of Splitfire, E3 and all that "snake oil" and you're dead right. There ain't any new plug technology. You gave good advice.
