I just bought a set of 6 NGK PFR8S8EG which came in Audi branded boxes, in my write up of what my car is/needs, I seem to have left the gap as ?.?mm which is not very helpful, and I've made no comment in my service record when fitting them, so, I'm guessing that I've left them set at whatever the NGK listing said they should be.
Edit:- okay I've checked on the NGK website and they quote 0.032" which translates into 0.8mm, so, thanks for making me get moving and clearing that up for my records!
