BS or BS?

[Ascinder]

That sounds very interesting...I myself just watched the video comparison of the traditional plug and the Pulse plug, and how much faster the flame front moved. To me it makes sense to want that so that more gas could theoretically be burned in the same time period. More complete combustion and sooner=more burned fuel/less waste, etc. Burning faster also equals burning hotter, so more pressure, and consequently more power. The claim that the Iridiums are 99.999% efficient is a somewhat relative term. They may be very efficient from a conductive standpoint, but that doesn't necessarily make them ideal. What are the so efficient in doing? I find it absolutely naive to believe they can be so close to 100% efficient at burning all the gas off in every different type of cylinder/piston/valve system that they are used in-sorry,but I'm calling some heavy BS on that. Also, higher horsepower can lead to higher efficiency if other factors are right. The only concern I have about the spark kicking off the flame front so much faster is detonation. There's a reason gas is used in engines the way it is. So you get a "slow", even burn, not an sharp, severe explosion like in a gun. I think the jury is definitely still out on this.

has anyone tried these plugs yet? all the ads look promising.. but we all know ads mean nothing

amazon reviews are split 50/50 5 star ratings and 1 star ratings.. everyone who doesnt like them has the same description.. rough idle, misfires.. occasionally black smoke and a whine through the radio.. one guy said they fried a coil pack.. another said his ECU fried a few weeks after install.. then others said they saw 1-2mpg increases (although one of them highly recommended a hydrogen generator and a conversion kit to run your engine on alcohol)

I'm not buying it. Maybe I'm way to simplistic in my thinking but:

We all know how well gasoline burns - if it didn't, it wouldn't be our fuel of choice. The spark just gets the process going. I don't think that 'post shadow' or multiple sparks or hotter sparks make enough of a difference to be worth any extra cost.

What does make a better spark plug is one that minimizes post erosion for longer life and by design isn't subject to fouling due to build up of carbon.

If they made that much of a difference wouldn't they come stock on the high end performance cars?

If they work they work 100% of the time. At 50-50 rating you have the BS artists the dreamers etc.

All you need is enough spark to ignite the mixture. More spark than that *if there is more* doesn't give better burn propigation.

I've seen similar items many times. Most are just an additional spark gap in series. ie: Nology.

If this was the greates thing ever NGK or Champion would have bought them out, and these plugs would be in EVERY new car today.

99% of the gas saving gizmos out there either don't work, or actually use more gas. Don't drink the Kool-Aid.

i would stick with a good set of NGK's...they are specifically designed for japanese cars and work the best of any plug...

i have tried every gizmo and brand on my integra...every one of them makes it misfire...NGK's...no problem....

every japanese car mechanic i have talked to says never run anything but NGK in japanese cars...so thats what i do, and i get great mileage and power...

TOM4BREN--- Ditto. I completely agree with everything you stated. You hit everything right on the mark. Well said.

Especially, "High Performance" cars like Lamborghini, Ferrari, Viper, Shelby, McClaren, ZR-1 & ZO6 Corvettes, etc. If we look at those cars as a Mentor/Role Model of what is essentially good by OEM factory standards, and using likewise products in our VX's, then we as VX owner's will be OK.

before I went to Moab last year....I considered these as replacements for my stock plugs...but found lots of conflicting info on them on the web. Bottom line...I went with the Denso Iridium's because I couldn't find enough positive feedback on the Pulstar's.

P.S.---I had great luck with SplitFire's in my Harley...that bike seemed to LOVE them! More MPG...more neck snapping torque! Put them in my Ram and I didn't notice any gains...but that bike sure seemed to likey!

Whoah - I'm not used to anyone taking me serious around here. I'd better be more careful about what I say from now on.
