Just learned about this and it sounds like it's a good idea in theory, but didn't know if it was just crap that was marketed right in their promotional material. See link: http://www.pulstarplug.com/

Anyone ever try these or know someone who has?

I've never seen or heard of these plugs, and at $25.00 per plug I won't be seeing them under my hood any time soon!......$150.00 for 6 spark plugs is insane!

Yeah, wicked steep $$$$ and I can't see the justification for it since the gains seem to be marginal in terms of only 2-3% improvement in MPG and equal percentage gains in HP and torque from what their analysis reports show. Just didn't know who has "real world" experience with these since every little bit counts, that is if these things actually work.

If there's anything to it, somebody will mass produce these things and sell them for an affordable price. For now, it looks to me like that $15000 exercise machine they advertise in the back of Popular Science or whatever that looks like an alien torture rack and claims to get you into perfect shape in like 4 minutes a day. Riiiiight.

I used them in my Armada. They delivered as promised; 10% better mileage. Power increase strictly butt dyno, not a lot. Will be using them in my Xterra.
