Well I decided test out the cold air wall similiar to Cold Air Intake Wall & Box kits

To do it I made one of my own using cardboard to seal of the area where the FIPK is located. Cliff notes is there is a noticeable 20-30 degree difference with the wall and the stock hood, stock cooling system.

Results?

Well it works, for a little while that is. Usually on a warm 50-7x degree day when the coolant temps reach 18x-189 the subsequent intake temps go anywhere from 50-80 degrees above ambient (highest being 13x).

With the wall in place on the same day temps only go 40-50 above ambient and I never saw anything much over 100 unless not in motion. When I parked the car and came back (shopping) and started her up again intake temps were at 129 from just sitting there with the engine off.

A little motion out of the parking lot and she dropped back down to 10x and once in traffic it was back down to 9x. Seems like the wall prevents direct the direct admission of air from the front manifold and radiator to the MAS but it can be overwelmed if you are idling for too long and their isn't adequate venting with the stock hood.

Still looking for some numbers from people with aftermarket hoods. Pretty sure one of those vented hoods in combination with this wall would be a direct shot of ambient to the MAS or pretty close.
