I think the point is that on a turbo motor the plugs dont last long enough or give you a performance gain to warrant the extra expense. are the densos better pugs, yes, is there any advantage, no.

Basicly yes ... IMO the biggest difference between the motorcraft coppers and the denso is durability - the coppers need to be changed much more frequently than the densos. I personally run the coppers because they are readily available locally and cheap & easy to change.
