Default Turbos don't like irridium / platinum

Speaking from experience, although the S4 may be an exception... If you run 1+ bar I would definitely go with plain ol plugs.

New Iridium vs. old oem. Who knows, new oem may have given same results? IMHO.

Default Stock is platinum...

I actually thought the same thing about Platinum and was surprised to see them installed.

Copper's melting point is 1981 degrees F.
Iridium's melting point is 4449 degrees F.
Platinum's melting point is 3224 degrees F.

Copper's Tensile strength is 20,000 PSI.
Iridium's Tensile Strength is 160,000 PSI.
Platinum's Tensile Strength is 20,000 PSI.

I think the issue people were having lie with the Bosch Platinum's and I think that's why Audi went NGK..

Default Yes

I didn't claim it to be better, like I said we had no hard data. Science proves it takes less power produce a good enough arc w/ iridium so you could theoretically run larger gaps. However with out the data on the coil pack it's all theory. Do what you want I'm just presenting another option

Default Re: Stock is platinum...

I have run NGK platinums in my DSM and without fail the car will start to miss past 18psi (1.2 bar). And yes I realize stock is platinum but I think that's more of a service issue for Audi than anything else seeing how much of a pita it is to get at the plugs.
