I'm wondering though. Assuming the holes were engineered into the original production they must have served a purpose that later was determined less desirable than the purpose and expense of installing block off plates. Do you think a performance engineer designed the holes to ensure sufficient air volume at WOT but later a sound engineer determined the whistle was undesirable and BMW decided that customers would complain about the noise in every day driving while not noticing a slight decrease in performance at WOT?
interesting theory????
