SML: Jacobs Electronics ignition coils. Anyone experience these?

[Don]

Am looking to enjoy the ride in a little more exciting and economical way.

I'm considering the Jacobs Electronics ignition coil. For about $300 (in my
case) they say it gives you a good increase in gas mileage,  hp, engine
reliability and engine life, and also helps the engine run a lot cleaner in
California (heavy duty plus at smog check time).

Does anyone have experience with these? Does it seem like a worthwhile
investment? I've heard of one guy raving about it but that's all I know (so
far). What do you think?

Thanks!
