Heh, they're glowplugs like on model aero engines, can't believe they got a patent.
I remember The RoadWarrior..To understand who he was, you have to go back to another time..the world was powered by the black fuel & the desert sprouted great cities..Gone now, swept away..two mighty warrior tribes went to war & touched off a blaze which engulfed them all. Without fuel, they were nothing..thundering machines sputtered & stopped..Only those mobile enough to scavenge, brutal enough to pillage would survive. The gangs took over the highways, ready to wage war for a tank of juice
I tend to keep fresh spark plugs in my car and swapped out the stock NGK plugs that had about 8,000 miles on them with the pulstar plugs and didn't notice any positive change, I did start to have my engine die at idle but that only lasted about 500 miles, I then got my electric car and haven't gone thru enough tanks of gas to get a solid number but it would appear that there are no changes, I'm tempted to put them in my moms car without telling her as she has a set driving style and mostly just drives to and from work and has always kept a gas log.
