The Duratec Sparkplug Sticky

[wickedgreyzx3]

if any of you posting about silver spark plugs read anything about my origninal post i wasn't going to talk about "designer" spark plugs, mods please clean this thread up

Sorry, I didn't realize this is a read only thread, that audience participation is not allowed, and that you are the supreme being of sparklplug knowledge.

My apologies.

As, stated before, that's incorrect. SIlver is the best electrical conductor of all metals.

Ok, so even if silver is the best conductor, we can all agree that the cost of such plugs would make plats and iridiums look like pennies on the dollar and way out of 99% of our cost ranges for plugs. True?

130k on stock plugs. My change will be to 103s.

False.. ANywhere from 8-15$ a plug- and NOlogy isn't the only one marketing silver electrode plugs. In the Goog search below, I spotted Bosch on the first page of search results.

Wasn't an earlier post quoting 18$ a plug at the dealer for some plat Motorcrafft ? I could be off by a few bucks, and it might have been in another thread- ther's been a spate of "sparky" threads in the past couple of days. The price of Ag plugs is below that- the "pennies on the dollar" (by comparison )is just not r valid.

ANyway, this is a good thread, not everyone needs Ag plugs. There is such a thing as bang for the buck regarding HP and mileage. But ,if the goal is to get all you can get out of the engine( and it seems like there's a few on this board with that goal) it is an option to consider.

My goal, presently, is to keep the skinny pedal steady, and stretch out as long as possible my visits to the gods of petroleum distillates.

I take it billie pretty much quoted from the nology and brisk ads...
The plugs liquid tagged are available easily, most likely within a couple miles of peoples homes, unlike ordering and waiting many days.
there was another company that came on here touting their plugs and what they had done on the bench and that they outdo anything... pretty much fell flat on their face when it came to dyno comparison, they slightly outdid stock (IIRC 1HP), while the 103s decimated both.
unless there is real world side by side tests, dont believe the designer hype about their ratings (most are bench tests where there is no actual load or heat stresses on the plug).
That is unless you like having sunshine blown up your butt.

Nope, I quoted from no links. I provided links to back up my statements regarding conductivity, resistivity, and thermal conductance, though. Had I quoted from any website you would have seen """""""""""""""""" with writing in between the ""'s.

You can check any text on electronics, physics, WIKI ,or Google "best electrical conductor". Let me help you....

Or talk to anyone involved in semiconductor manf/ packaging

Back on track...

mods please clean up thread, this thread is about OE and copper spark plugs, not rediculously expesnive designer spark plugs that there is little to no evidence or testing done on them and only claims by the manufacture.

Metallurgy in electronics is completely different than in a combustive environment.

Annealing basically softens metal. I only offerred up the semiconductor analog, because, if it wasn't the best conductor, manf's would use something different.
