HAs any one tried these new Pulstar spark plugs?

 

To change the power out put, it has to either reduce the amps or the voltage so it can increase the other. So either it is a gimick to boost their resistor plugs or it has some kind of transformer. Either way, I'd rather do the same thing with an MSD or like ignition upgrade.

 

I saw a test done with these plugs on "HorsePower TV", they gained 6 hp peak on the dyno. At $25 a plug ($250+) a set dosn't seem worth it.

 

Considering the user has two posts, both about these plugs, I'd say its spam. Change any worn out plug and you're going to see similar improvements, no matter what you change them to so long as the gap and heat range is correct.
