Spark plugs - what gap on N55 M2
I cannot find any info anywhere on what should be the gap on the stock M2 spark plugs?
I know some here have done this DIY already, hoping someone can point me to a link explaining what exactly I should set the gap to (stock tune, stock spark plug).
Good advice I received in another thread was to never install spark plugs without checking the gap first, but can't find the info on what the measure should be anywhere, lol!
