[V6-12v] how do you test for spark?

[James Whitehouse]

FYI - in Euro models, the OEM part has been changed by Audi from Bosch to
NGK (same three-electrode plug, but they reckon higher quality and
longevity, not that I've noticed any difference in running, in practice).
Tom's right though, the gap is still factory adjusted whether you go
bosch/ngk, you don't set the gap on these engines, just buy the correct
plugs.
