Pulstar plugs?? Supposedly 6-8% improved torque?? What cha think?
Here is the info I found.

ALBUQUERQUE, N.M., Jan. 28 /PRNewswire/ -- Enerpulse, Inc. has released its Pulstar(TM) model DG1 pulse plug, designed for late model year Mercedes and Infiniti cars. Pulstar(TM) pulse plugs, which hold eight U.S. and foreign patents, were developed as a drop-in replacement for all spark plugs, including iridium spark plugs. They are designed to more efficiently ignite the fuel in an engine's cylinders which dramatically increases horsepower, torque and fuel economy. Pulse plugs look and fit like spark plugs, but unlike spark plugs, pulse plugs contain an integral capacitor, which dramatically boosts peak spark power from 50 watts in spark plugs to 1,000,000 watts in pulse plugs. http://www.pulstarplug.com/howtheywork.html
The Pulstar(TM) DG1 pulse plug was designed for luxury car owners who want better fuel economy and the latest technology without sacrificing performance. European performance model Mercedes such as the G55 AMG and virtually all of the late model Infiniti vehicles, including the big QX56, 5.6 liter V8, respond well to the DG1 pulse plug. Tests conducted at Enerpulse, Inc. show that both the Mercedes and Infiniti can experience a 4%-8% gain in torque with a 6%-8% improvement in fuel economy. http://www.pulstarplug.com/fueleconomy.html
DG1 lasts for about 50,000 miles in these luxury cars, meaning that the return on investment after installing Pulstar(TM) pulse plugs is about 300% over the life of the plugs (about 4 years in normal driving situations). More importantly, Pulstar(TM) DG1 pulse plugs will enhance the driving experience through better throttle response, faster acceleration and pronounced low-end engine torque, all of which add to the luxury of a luxury car.
Enerpulse, Inc., a privately held company headquartered in Albuquerque, N.M., was founded in 1996. The company develops environmentally friendly ignition products through the application of pulse power technology. For more information, visit http://www.pulstarplug.com.

I have a QX56, so maybe I'll try it first. Watch me grenade the wife's car.... you'll never hear from me again

The largest improvement I have ever seen was on a built
BPM 12 liter V12 gas engine with 6 IDA 48 Webber's.
In a test cell, 12 hour break in and oil changed first day.
Day two 6 hours full load @ 900-903 hp.
Day three change plugs Bosh to NGK 6 hours full load 918-921 hp.
No question the NGKs ran better but only 2%

i remember the same claims from the platnums and the dual electrod plugs years ago yet most tuners are still using the same old ngk, champion, or bosch plugs they always have.

The insulator is straight, leaving a shorter path for the spark to arch to ground. A typical plug had ridges there for a reason... and it's not fashion.
1 million watts of power eh? Funny that.. it must have a nuclear power plant inside the plug to magnify the power of the ignition system. Let's assume 50,000 volts of ignition current. That's about 20 amps of juice per ignition pulse. Yeah.. well.. the wiring on our cars won't push 20 amps to the coil(s) on a good day, once, much less several thousand times a minute!
I love this stuff... 8 patents.. WOW! Where are the patent numbers, or are these 8 patents just provisional? How odd.. the USPTO does not seem to know anything about 'Pulstar', 'Pulse Plug', and not even the name 'company'.

I may be wrong but I think the plugs violate some basic laws of physics.

You cannot order the plugs for the E55, you need to order for a different 55 model if youn want em.. The website has zero plugs avail for the 63..
Tell um bout mbworld.org being the worlds largest Mercedes forum. Would love to see how far we could push before they start getting nervous.
Don't forget these are supposedly "for Infiniti and Mercedes", notice the chart of vehicles tested.

I bet the plugs they pulled out of some of these cars needed changing anyway.
The other thing about their pitch is that it implies this large amount of loss. Looking at the plug diagram I swear it looks like they have an inductor. At 210C the inductor stops being an inductor!! By the way, check this out http://www.enerpulse.com/index.html same type of product designed to go onto a normal spark plug. I should buy one and tear it apart.
What is different about a pulse plug is that instead of heating ignition parts during the ionization phase, this energy is stored in the integral circuit inside the pulse plug. When the ignition power overcomes the resistance in the spark gap, the pulse circuit discharges all of its accumulated power - 1 million watts - in 2 billionths of a second!(That implies there must be a timing delay between the coil and the spark. The normal system started the spark 29.998 millionths of a second sooner than the new plug)
Plus, I think their diagram is wrong! The spark initiates as the switch on the primary opens, they show the opposite. Anyone remember their distributor and spark gap? It was closed most of the time until the lobe came by and opened them. They are describing a forward transformer, but the coils are all flybacks (don't worry, it's my job so I have to know the difference). Also, all our cars have individual coils for each spark plug and the points have been replaced by a transistor (MOSFET) so the length of the wire to the plug is shorter than the wire to the battery. A lot shorter.
Since this stuff has been on the market for some time I checked the patent office. Nothing.
Here is an old opinion from 2005 http://forum.ih8mud.com/545758-post7.html
and our own forum in 2003 https://mbworld.org/forums/c32-amg-c55-amg-w203/33408-evosport-do-you-think-worth-testing.html
Just a load of crap.
You would need to do the testing thousands of times for each plug to determine if there was any real (statistically meaningful) difference.
The OEM plug is just as likely to be equivalent to the iridium plugs, from the power 'generation' perspective.
