What's the word on these new "halo" spark plugs? Any feedback is appreciated.

They don't even make a plug for the Corvette ... but even if they did ..... snake oil.

I had VERY poor results with E3 Diamondfires in my '02 Z06, they lasted about 30 minutes before they started misfiring to the point that the check engine light came on. Took them back to PepBoys for a no questions asked refund.
