Has anyone tried these sparkplugs ?

I would like to know if anyone has tried these and notice any measurable difference. I am very hesitant to try any aftermarket items. If they are that good why doesn't any car manufacture use them ?

I actually emailed them about sending me a set for my Subaru for dyno testing. They sounded interested and asked for my address but nothing has come of it yet. The concept seems valid though, it should yield a much more powerful, and shorter duration spark than a regular spark-plug. I may give them a try on my Subaru after I get the B381's on it. If it wasn't for that darn budget. . .

I just wish they'd hurry up and get these on the market:

I've looked at that pulstar site and find issue with some the electrical theory behind their claims. For instance this: https://www.pulstarplug.com/howtheywork.html

"Instead of 50 watts of peak power typical of all spark plugs, pulse plugs deliver up to 10 times more peak power."

Where does this extra power come from? Either the volts are increased or the amps are increased. Watts=volts x amps. A 50,000 volt spark will have only 1mA or .001 amps to net out 50 watts. A capacitor or capacitive discharge does not amplify neither volts nor amps, but only stores them. Where does this additional wattage come from?

Yep, the whole thing sounds fishy to me.

Their pictures in their adverts could easily be doctored, makes me wonder.

I am always suspect of new things like that.

You could try them, but if they were really as good as they say, then all car mfg. would install them from the factory. All car mfg. want more power/mpg in their vehicles........... Just my opinion.

Froggy8150 may have come close to the secret. You need to change the duration of the spark. 50 W x 3 us (microseconds without the mu) is the same energy as 500 W x 300 nanoseconds. Energy is conserved, power is increased over a shorter time interval. The question is, does the gasoline care?

Those plugs are very interesting I wonder it there better than Firestorm plugs?

thanks. And does the wattage, spread over a period of time, really see any increase? Their plug sounds a lot like the MSD capacitive discharge ignitions I used to read about 10 years ago.

I've used pulstars as well as 2-3 friends of mine. (we're all friends with a guy who works for pulstar and sent him old car parts for his research) the mutual consensus is that they're like going from old, worn out, huge-gap plugs to new ones... except starting with new ones. So yes, there is a difference in power and liveliness of the engine across the entire powerband but not a huge amount.
