Do you mean atmosphere water? If so, what provisions did BMW allow? Same provisions. Maybe a little water may enter the rear opening, at stand still, but in the case of the exit scoop, there will be an Al2 divertor that will also help channel water away from the spark plugs.

 

so .... in a down pour the water won't come in the rear and pour onto the engine? cool my mistake . meds time .; btw .

 

I'd still be looking at the road ahead! You should be too.

 

at least until the steam forces you to pull over . myob
