I ran across an advertisement for these plugs in this months Boating magizine. Has anyone tired/heard of this technology? Its completely new to me and as we all know, you can rarely trust an advertisers claims on performance.

In my case a full set for my 450SL-C would run me over $200

I have no idea... sticking a capacitor inside the spark plug sounds like a good thing, but I wonder what it would do to the car's electronics...

I would be tempted to stick a set on the BMW to see what happens. The Suburban doesn't get driven much these days...

Common sense tells me this is just snake oil.

Here's a discussion off of another forum:

Underwhelming evidence that it may work better than regular spark plugs.

Sounds like snake oil to me, unless you can personally find a user of these plugs to verify.. "Joe B says "They're great"" doesn't cut it..

Just MHO...

Kind of reminds me of those capacitor wires they sold a while back. Same claims, dubious results. Sounds like they just moved the capacitor down one more component to see if they can hook a few more suckers.

Spark plugs are miracles in their own right. There is not one use for capacitors in plugs. Spark plugs provide a gap to spark. Cold spark plugs are good for highway use and hot are good for city use.
A Capacitor's job is the hydraulic equilivant to an accumulator. I see no reason to store energy inside a spark plug.

They might come in the same box as extra slippery oil

They are just a shiny metal version of snake oil. The spark plug's only job is to arc a spark across the gap, the rest of the reaction is all dependent on the design of the engine cylinder and how it spreads the flame kernel.
