Best material to use in home made airbox?

After looking at the prices of race spec carbon airboxs I've decided to make my own.
I'm going to "borrow"
This design for use with my jenvey throttle bodies.
I'm using 25mm air horns, so it would leave me around 75mm from intake to top of the airbox.
The build itself I think I've figured out, one thing I'm unsure of is what to use as the filter.
The easiest solution I think would be foam, but I'm unsure if this is the best material to use.
Anyone got any experience or knowledge of what I should be looking at using?

No.
I have a large roll of Alu fibre I piced up a couple of years back.
Been wanting something to build with it ever since lol
This has just been suggested to me.

there are a few ways to do this, one is the full race way and dont fit a filter but thats not practical for the road, another is to make your air box large enough to fit a flat panel filter inside it,say a K&N, so you would have the air enrty into the box then it goes through the flat panel filter and meets up with your inlet trumpets. The next one is a little more expensive, i'm trying to remember where we got the filters for the F3 cars because they are tapered,they start at 70mm diameter at the base and taper down to 15mm, they are about 150-200mm long and are designed to fit inside the tubing that feeds the airbox. it could have been ITG but mental block has hit me!
EDITED TO ADD
just found a picture of one very similar, its the tall one on the left, you could even get some foam sheet and make this yourself,use evo-stick to glue the seams.
get some flat foam sheet, ideally two grades, one fairly course, course enough to be able to see your hand on the other side and another finer grade that you cant see through yet isnt a restriction when you blow through it, put your hand on the other side as you blow, if you can feel the air then thats enough. cut the material so you can make a long (200mm) tapered cone from it and also you need to get the diameter of the large end to match the internal diameter of your feed tube,5mm larger is better,dont stick the sheets together! now take the fine sheet and roll it into the cone shape and stick the seams together with glue, let it cure, now wrap the course foam around the fine cone and stick its seams together.trim the length and neaten each end and apply a fine bead of glue around each end to bond the two sheets together.thats your filter, now all thats left is to put it into your feed pipe and stick the large end to the tube,put it somewhere that you can easily get to it to clean and oil. hope that lot makes sense!
