my opinion is that they are a gimmic. made my car run like crap. put the old plugs back in and it ran fine. i sent them back and got my money back.

can i tell you a secret?
there is very little new technology, just alot of hoaxs

This thread needs more !!!!!!!! to emphasize...something...

Google is your friend. The Pulse plugs have been around for a while and a number of people have used them.

Just realize that the plug ignites the fuel. A better plug will not help any more unless the plug it is replacing is having trouble igniting the fuel (large gap, fouling, etc.) You would experience misfires if this was happening. After the fuel is ignited, there really isn't anything more the spark plug does. The fuel will simply burn up at a given speed based off its octane.

So what does a $1 cheapy copper plug do worse than the super whatever plug you might be looking at?

well, technically if the plug can create multiple sparks at the same time it should create multiple flame fronts which should have some effect on the combustion. how and if it would be good, I couldn't say. I've thought about this because aircraft engines (and some auto engines) have two ignition systems so two plugs fire at the same time (or nearly the same time) and it makes a very noticeable difference in engine roughness and power output! The plug locations on aircraft engines are opposite sides of the CC so the epicenter of the combustion events couldn't be replicated with a single plug.

On aircraft at least, isn't some of this also just for redundancy? I'm pretty sure most/all piston aircraft have completely separate dual ignition systems, just in case one fails. . .That said, dual-plugging is rather popular mod among the BMW airhead motorcycles. . .with all sorts of partially and un-substantiated claims of wild power increases.

I had dual plugs in a BMW r100. Just take a wire off one and drive it- you can see the difference, It is significant. In my airplane, at 1700 RPM dropping one mag results in a loss of 100 rpm

Not without moving it won't. If the plug ignites the fuel near it, there won't be any fuel left to ignite a second time.

If you have two plugs, you can start two flame fronts from different locations. That would certainly change the engine's performance. But it wouldn't be the same as having a single plug fire multiple times.

Oh yes, the primary reason for having two ignition systems is for reliability and safety, no doubt. I was just saying that it ALSO results in more performance.

Who said anything about the same plug firing multiple times? multiple sparks at the same time @ different locations is the key.

Now if one plug can fire multiple sparks across multiple electrode gaps, it would effectively be just like having multiple, very close together plugs. And I think that may result in little no measurable gain in combustion "performance" because of the proximity of the combustion epicenters to eachother.

Hope that make my previous statement more clear.

In any case, this is not how the Pulse plug works and there are no plugs/ignition systems capable of doing such a thing.

Uh oh, 75 rpm mag drop is the max allowed!

I don't think I have seen a 75 rpm mag drop on new plugs and bendix mags even with retarded timing.

i bet you believe that the slap chop is greatest kitchen item to be invented? YOUR EJ253 runs best with NGK or Champion platinum or copper plugs. Please do not waste money on "pulse plugs" but if you must try the latest in plug tech spring for a set of Split Fires!

It's 125 on a lycoming O-320

i dont think creating multiple flame fronts will do anything for your boxer except cause pre detonation and too many explosions on top of the piston while its on the exhaust stroke. the pulse plugs are significant because it creates more of an expanding force on the air fuel mixture instead of an explosion. obviously it ignites the mixture, however it aids into a stronger combustion force on to the piston which we all know equals some kinda hp gain. modified mag did a little write up on them. you can find the pdf of the article with this link --> http://www.pulstar.com/pdf/Modified_April2008.pdf
