Has anyone tried them yet.
There is a power and mileage increase claim.
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 factory 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'm not gonna waste my money on pulstar............
a personal friend of mine, is one of the first few Sky redline who used those plugs. He is a forum member (GetAboutRL). The plugs crapped out on him....and he was lucky enough to get them out of his car before destroying his engine....
When I asked the guy at the auto parts store about these plugs he said they are the best. I said how much. He said $24.99 EACH. I asked why they are so much. He told me they are the best. I asked why are they the best. he said "They are just the best spark plug sold."
I wasn't sold. Bought NGKs instead. I think I spent 12 bucks for all four.
