Personally, I can't see the point in having a pod filter if you're gonna box it up?
The reason you put the pod on is to increase air flow.
If you box it up you are reducing airflow to the size of inlet on the box/ induction pipe, are you not?
Would be better to keep the stock box with a high flow filter panel then wouldn't it?
or
a partition to keep direct heat might help???
Just my 2c,
