Elusive Spark Plug Gap Size
Never thought I'd get such mixed information on a simple thing as spark plug gap size (see pic).
Quite different sizes listed by NGK and my Bentley Manual for my 2000 Audi A6 2.7T.
Bentley say .016" - .024, while NGK says .032".
Plugs NGK PFR6Q Laser Platinum.
Can someone confirm what gaps their manuals callout for my vehicle?

Elsawin confirms Bentley. 0.4 to 0.6mm...
FYI, Elsawin says I needed to be running 0.016 to 0.024" as well on my 2.8 (ATQ), but the NGK standard gap on BKR6EQUP was 0.032". I was not ready to gap 4 prong plug... I installed them without adjusting the gaps. They worked fine.
