2011 n18 s

 

The Bentley manual says that the spark plug gap is not adjustable.

 

Dave types faster than me!

S plugs that I've seen always say "sold pre-gapped"

The plugs for modern engines with Turbo etc use very strong metals in the electrodes ... this is one reason they are $$, and have life expectancies much beyond plugs of old. The very hard metals make adjusting the gap an unlikely process in the typical home garage. The days of tapping on the work bench to close a gap are gone ....

here's MiniMania's plug application guide ...
