Has anyone either seen these before or have even tried them??

I was doing a bit of googling, as you do. About running the Z18XE on E10 fuel. And these came up. http://www.magnumtuning.com/en/detai...ine-serial-nr-

I am already running Denso Iridium Twin Tip plugs. Which as made quite a difference I must add

They do mentioned that they are also good for normal fuel as well, not just Ethanol blend.

Interesting or as they say "Just Bullsh!t"
