My VW Mk6 GTI has an APR setting and they recommend a 0.024" (0.023" - 0.025") gap. This means they must be crimped with a factory preset gap of .032". Another reputable tuning company requires .028", so I think the factory wide gap works as intended. Note that these spark plugs are 1 stop colder than the standard GTI's iridium, which is brittle, so if you scratch the electrode, splitting the steel wire or turning the dial indicator to adjust it can do more harm than good. Leave it as an easy winter project.
