What is the length of the 320i runner as compared to the stock 530i runner? They appear the same to me,but an archive post says they are 2" longer! Another post says the difference in width is 30mm an 34 mm. I can understand that a larger runner would make the engine breathe better...can you clarify the difference between the 320i and stock?
