I hope you're joking

There's an extremely little amount to gain in the spark area of engines. The biggest advantage this would have is individual combustion chamber monitoring, which BMW uses through the spark plug on the M5 for instance. Unless this eliminates the ignition coil, which I doubt, the only wear part its replacing on modern cars is the spark plug itself, which is quite simply the least expensive part to replace.

I dont see big changes ahead, even if it DOES work. How expensive are these stupid things, and are they still as easy to replace as spark plugs?
