the amount of air an engine sucks in per cycle is limited. question is ... is the stock airbox larger than that volume?
and finally, the MWR has a least one advantage I see, reducing the amount of turbulence around the intake horns.
I hate how close the stock filter sits to the intake horns. that cannot help air flow during an intake cycle even it's a K&N filter.
so... as long as the MWR is allowing enough air into the airbox based on flow and surface area, then it should have an advantage. If the surface area isn't sufficient then it may actually limit the airflow
Very interesting.
The MWR set up attempts to create some space between the filter and intake stacks/horns, so they have tried to address the problem. I wonder if there was a way of affixing a panel filter at the very top of the airbox?
