[s-cars] Which Spark Plugs?

[Radek]

Thanks to all for your responses.  I wasn't looking to incite any wars, what 
I meant by "rumours" was my vague recollection that turbo Audis, as well as 
the V8Q, don't like some Bosch plugs.  Thanks to Scott for a detailed 
explanation.  NGK iridiums are on order, the price was right at Rock Auto.
Best regards;

Radek.
