Indexing new plugs is the best thing to do to help combustion.
Old worn plugs waste gas and have weak ignition.
There is power to be had in ignition area! But not big hp like there claims![/QUOTE]
This works on the dyno.

Indexing is when you screw in the spark plug only a certain amount so that you know the end of the electrode is pointing in a certain direction inside the combustion chamber--usually directly between the intake and exhaust valves. You can't leave the plugs loose in the heads, so to index them properly you have to have a set of shims made for the job. Then you have to figure out the thickness you have to use to get the plug pointed in the right direction.
Indexing is good for more inefficient combustion chambers (usually found on stock heads). But if you are using high performance heads the process of indexing is usually less efficient.

Halltech has a set of these for dyno testing at Katech. I am leaving the door open for a thumbs up or down on a real engine dyno.
Jason will make the dyno A-B-A available when finished.

Pulsar Spark Plugs
All this spark plug horsepower increase and better gas mileage is all about the manufacture who makes the wildest claim makes the most money.99% of their claims are BS.When I was a teen just starting to drive I would look in the JC Whitney catalog to see how I could get my Dad's slant 6 Dodge to run faster,Well pop and I sat down one day and added up all the gas saving and horsepower increasing gimicks the JC had and we came out with a stock slant 6 that would make 300 HP and would make more gas than it used.

While it might be BS, it has been estimated that a person can buy time and make upwards of ten million dollars from naive people before being shutdown due to false claims and customer complaints.

So, I guess this means you need a set of 12 or 16 to wind up with 8 that will go into the engine. .... 
Gets to be expensive at what they're charging, per plug.

They will be in all of my cars from now on. I am waiting for the 12mm to come out; then all of my cars will have the pulse plugs.

I have used them in both my Vette and my 5.7 Hemi Charger and they are Great. A very noticeable increase in seat of the pants torque and horsepower. The mileage claim only works if you keep your foot out of it. I can see already that with the great increase of feel that my right foot probably will not let me enjoy the mileage increase. But what are performance car for ? ? I purchased my plugs from a speed shop that had a display that showed both NKG and Pulse plugs. The difference was night and day in the amount of spark the pulse plug put out. It is only common sense that the quicker you ignite the fuel the quicker and more complete the burn which gives more power and a by product of better mileage and less emissions.

Hi everyone,
What makes the spark between the electrodes is as follows.
When a coil has voltage applied to it, the coil charges. No spark occurs until the voltage is removed. When the voltage is removed, the magnetic flux around the coil collapses. The law of physics states that when this occurs that current will flow within the coil and must flow. The voltage keeps increasing as the magnetic flux collapses. Once the voltage builds to a point, current jumps the gap. ( Voltage does not flow, only current flows ) Because the spark gap is the path of less resistance, a spark occurs across the electrodes. One of the worst things to do is run an engine with a spark plug wire off. Doing so makes the internal of the coil the path of least resistance shorting out the coil. This can damage the coil.

I went to a speed shop a while back and they had a display with some high tech spark plug wires made by Nology . They allowed a standard spark-plug with a standard coil to significantly increase output. They were something like $240. 
Nice eye catching display. Funny,,,,,,I have not seen these wires or PULSAR plugs on ANY Car maker OEM application, Race Engine or Commercial application. If they were that good/dependable or made that much improvement,,,
,,,,don't you think that the OEM or NASCAR wouldn't be using them to make their cars better.
Save your hard earned cash for something that prooven like headers or a cold ait intake.

I agree 47 hp from plugs? No-way.
But answer this................Why does indexing spark plugs help?
If its just a spark then where does this gain come from? Forget engineers,
lets here from the racers and engine builders w/ hands on.

Big Fat Zero
We purchased a set of these for our E85 motor, and ran out of dyno time a few months ago.
During installation, three plugs broke just installing them.
They sent out new plugs, supposedly non breakable, and Katech dynoed them today.
Jason emailed: " A Big Fat Zero"
So they might help with mileage on a car like a Prius, but forget power increases.
