I saw on a thread once that the bi-turbo diesel cowl fits and it doesnt have a big block restricting airflow to the magnum. Hard to find one though. I also wouldn’t be opposed to cutting that hump out and filling in the gap somehow.I see you cut open the cover like I did for the big mouth. You should add a strip of foam to the driver side of the opening to direct all the air to the intake. And I honestly didn't expect to gain anything with this CAI since I already had a K&N in the stock box but I picked up 1 mpg. Performance wise I felt no difference.
Look at my thread and see how a added the foam. Pushes all the air to the intake vs needlessly to the driver side.I saw on a thread once that the bi-turbo diesel cowl fits and it doesnt have a big block restricting airflow to the magnum.
