Would anyone know where to find the spark plug gap specs for the 2000 a6 4.2 engine. It's not listed anywhere in my owners material, I called two Audi dealerships and they didn't know either, telling me the plugs they use come pre-gapped and they had no reference for gap specs? What the !#$?&
I did buy some Bosch plugs that came pre-gapped, but I would like to know just for the hell of it.
