I've just recently received my MCS
after many months of expectation and review of product literature [including study of these posts]and have one simple question: The "stock" air induction to the "S" is, I believe, already a closed, cold air induction system which recieves air initialy from just behind the grill, where it is carried to a closed "airbox", through a filter, and on through the engine. This appears to me to be the essence of a "cold air induction system". As for the aftermarket products from Rogue, Pipercross, Alty, etc. - with the exception of the Alty [which adds a certain amount of air from the back cowl], the all appear to work much the same. I have added a higher performance K&N drop in filter to the stock system.
My question is, rather than simply change the configuration/type of filter [cone], why would it not be more efficient to clear the space from the grill which immediately opens in front of the portal, or air-inlet, near the front [and on the driver's side] of the radiator?
If you notice, the front grill does not extend its openings to the far corner, which is where this portal lies - this would allow a greater and more direct stream of air to enter. And, why didn't MINI do this in the first place? Water, perhaps? Wouldn't the Alta also let in water from a different location [below the windshield]? Thanks for any feedback.
