I just read about it in Popular Science July 2007.
20,000 times more powerful than ordinary plugs spark.
1 million watts of peak power versus 50 watts.

Has anyone tried them yet.
There is a power and mileage increase claim.

Sounds like they have a built in capacitor.

A spark in the combustion chamber has one job and one job only...ignite the mixture. Once ignition has been obtained, the flame front progresses across the combustion chamber regardless of the manner in which ignition occurred. The average power delivered by the spark of each spark plug is about the same and the energy delivered is about the same too...based on their numbers, about .0015 watt-seconds for conventional plugs vs .002 watt-seconds for this scam plug.

I can make a case for the Pulstar plug making less power. They say their spark lasts 2 billionths of a second while in conventional plugs the spark lasts 30 milllionths of a second. That means there is a shorter amount of time the A/F mixture is exposed to a means of igniting, so if the swirling mixture isn't exactly the right ratio at the point of the Pulstar when it gets its' short burst, a misfire will result causing a reduction in power and with the new OBD II system, it'll throw an "engine misfire" code. The longer duration of the conventional plug means a longer opportunity to ignite a marginal mixture. This is like an engine that makes high peak power but only in a very narrow, very high RPM range vs an engine that has less peak power but it's average power over the RPM band used during acceleration (usuable power band) is much greater. The engine with less peak power will kick the high peak power engine's butt all the way down the quarter mile.

Just another company preying on the ignorance of the general public in these times of high gas prices. Put it in the same category as the "Tornado" device et al that claim gains in HP and MPG with a simple device that's cheap enough for people to say "what the hell, it's not much money if it doesn't work", but they make a killing because it cost them pennies on the dollar to produce. Whenever you see one of these simple "devices", ask yourself in these times of high gas prices, EPA demands for higher MPG, and the consumers clamouring for high MPG cars, why don't we see any single car manufacturer putting these gas saving/power making devices on their cars from the facory so they can be the first with a car getting 100 MPG???

But there will always be ignorant people or those looking to get something for nothing that'll buy these things...much like what's going on in the world of hybrid cars where people think they are saving money when in fact they are much more expensive. I laugh at Prius owners when I ask them if they realize they'll have to drive the car for 20 years/800,000 miles just to get to break even on the extra money they spent for their "money saving" purchase. The look on their face is priceless when I show them the math...even better when I tell them the car will never last that long.

I tell them about the great MPG of the 'Vettes and they slap their head and say "I could've had a V8!"

Well, that about sums it up

man! that's too much reading! but great write-up!

How do you explain the fact that Sandia Labs helped develope this plug?

I went back and looked at the writeups about this plug and then tried to work out the math. Now its late but here's what I got: 1 Watt = 1 Joule/sec. So 1000000 watts = 1000000 Joules /.000000002 sec or .002 Joules. Regular plugs are 50 watts=50 Joules/.00003 or .0015 Joules. That seems to be a 33% increase in power being expended in the combustion chamber. Since the duration is shorter the spark is hotter and leaner mixtures will ignite better. I think if we ignore anything we don't understand we will miss advances unless we make them. Somebody check my math and comment.

doesn't the coil play a part in how much energy the plug expels?

You never know until you try it. They said the plane would never fly too and they also said the earth was flat.

1.0 anything divided by any 0.02 is going to be a number with a 5 in it.

Pulstar Pulse Plugs come with a 30 day money back garantee, So try them and if your not happy then return them. The results are amazing. If this product didnt do what they say it is suppose to do then why would they offer this garantee.

We've got Bosch Platinums with the 2 or 4 or even 17 prong electrodes, the Splitfire BS, even the Brisk (Lamborghini plugs) that I was influenced into trying...all crap.
Sometimes you simply cannot reinvent the wheel, even if it involves a super conductive, flux capacitor driven, defribulating pinpoint laser spark.

The ONLY spark plugs I would ever use in a naturally aspirated LSx motor (other than the AC Delcos that it has in it until I remove them) is the NGK TR55...not platinums, not Iridiums, just plain old $2.25 TR55s.

AintQik

Marc, are you kidding? I run TR6s ... I think. Maybe they are 55s. Too many cars.

AORoads

because of 100 sets sold, even if 99 said it didn't work, only 3 would return it. it "sounds" good, and that's why they do it. the guarantee has absolutely nothing to do with how, if or when they will work. it is called "marketing", and a calculated risk that some companies make.

C8-Vette

I agree, Orville and Chris were wright or right!!

LS1LT1

TR6 for nitrous (and maybe F.I.)....TR55 for NA.

Rich Z

$25 a pop for these things?!? Unless they make a SUBSTANTIAL difference in a car, they would be better off called the BendOver Plugs.

Sandia Labs is a National asset looking for a purpose to stick around. Originally set up to do research and develop nuclear weapons they now are relegated to developing spark plugs etc. Big org - big payroll - no specific job.

One of my first hand experiences was to pay them $1.1 M over the course of 2 years to monitor the development of a new surface to air missile system for the Navy. The "Statement of Work" between the Navy & Sandia contained 28 items they were to perform. At the end of the 2 years 3 had been done. I know it’s an isolated case, and I know it was over 10 years ago, but I am skeptical of any work coming from Sandia.
