They use those plugs because they last 100k miles.
That’s the only reason for it.
They don’t reduce misfires. They only help fuel mileage when a different type of plug is used up.
Replace the plugs and there is no difference.
Plus, it’s far harder light those rare earth metal plugs.
The ONLY think a plug like that does is lighten you wallet.
Stay away from that stuff unless you love to burn money and sound cool on the internet.
