I had them in my '06 Mega. They gave me about 1 to 2 mpg gain. I didn't notice any power gain.
I think I'd do it again if I had another gasser. I like that they will last longer than the champs and you don't have the cracking issues/worries of the platinum plugs.
The E3's are gonna cost you a Benjamin where as Champs are gonna cost about 30 bucks. BUT, if the E3's last 4 times as long (as advertized) as the Champs then you end up saving 30 bucks and about 6 hours of frustration over the life of the plugs.
