Wouldn't it hypothetically be better to lessen the distance traveled between the air filters and the engine? Possibly more efficient since the air doesn't have to travel a longer distance? Or does that not make a difference at all?
i.e. Injen DCI vs. BMS/Vishnu DCI?
I could be wrong, but I thought it made sense........
