I retract the comment about radioactive elements in sparkplug electrodes.

ENGINE VOLTAGE REQUIREMENTS USING SPARK PLUGS PRE-IONIZED WITH RADIOACTIVE GOLD



Edit: at least with Beta radiation. With Alpha radiation there may still be a possible improvement.

Edit Edit: it would help with cold starting though

I often question these numbers as they seem to refer to the after cat burn rate, where your fuel gets burnt is more important than how much of it eventually burns. When a typical Detroit motor is running open loop with a 10-12:1 AF ratio 95% of the fuel cannot burn completely in the motor because there isn't enough air.

I am always reminded of the funny cars with the flames coming out of the tailpipe.

Steady state at full operating temperature I don't doubt 95%+ is possible, but during acceleration, warm up or most any other time including idling I doubt anywhere near 95%. Take the cat off a warmed up modern car and take a whiff of the exhaust, if it smells like gas it isn't burning 99%.

well after I did the headers and other mods. i was at the track and got kicked off for the night because i dumped raw fuel out the tail pipe to the 60' mark. so off to the dyno and tuner i go. a few hours later we got the tune right. I can say the chevy tunes are easier to do and chevy tuners are easy to come by.

I believe that most of the difference goes away if the timing is advanced when running on single plugs. Longer flame travel distance on single ignition needs more spark advance.

The other, often overlooked fact of multi-ground strap plugs is that they take up more space in the combustion chamber, and bump compression slightly.

I had a Chevy Prizm with the 1.8L DOHC 1ZZFE engine, and it actually REQUIRED these twin-electrode Denso plugs. :shrug: Go figure.

I miss that car. Blew a connecting rod through the oil pan.

Got 34MPG no matter how I drove it.

Wow, I think I would like that requirement. I'd iesearch it until I found the Yoda who knew why. Here's an old news release from 2010 :

...plus, all those metal straps begin to act like both a "heat-sink" and mechanical "shield" around the central element...two physical events that actually reduce the chances of proper, reliable, operation!
