If you believe that I'll sell you the Golden Gate Bridge. You're only going to have so much juice coming out of the coil and through the plug wires and only so much spark regardless of what type of spark plug you have. More bullshit designed to take advantage of people who want more mileage. Short of installing a diesel or towing it, you're not going to get spectacular mileage out of a Land Rover or spectacular power increases unless you want to do some major work to the engine.

I saw these a while back in popular science and decided against them...

Some interesting discussion here.

And here is about the closest thing to scientific test results I could find.

Assuming I could get a 2.7% increase in mileage as described in the test above, I would save about $40 per year over 6000 miles of driving. So the break even point for $200 worth of plugs would be about 5 years or 30k miles of driving. Not worth it in my opinion, especially since I doubt I would even see a 2.7% difference.

Yeah, I was just throwing it out there since I know how much we all love our fancy ass spark plugs.

Looks like they are suposed to do the exect same thing as an MSD system does, in theory they actually would work well, but I can't see those doing much of anything.
