DISCLAIMER: I have done some extensive searching on this subject, and if I missed it, please give me the link to where I should look.

I am thinking about building an intake housing for an Apex Intake, has anyone done this before?
Anyone have the dimensions to build this?
Any advice?

My main goal is to filter the cold air up and block "most" of the hot air. I am not necessarily looking for a perfect solution, just something to help direct the cooler air to the intake.

Thank you for your help!
