Outer Limits 4x4 Board

G'day,
I'm after a larger airbox that'll fit in the stock position with 4inch inlet/outlet. I have modified the stock airbox for a temporary fix to get it back out on the road but it has a rather tight choke point where the 4inch pipe is welded on to the small toyota 70mm outlet and it's feeding a hungry Ls1. What has everyone else fitted up?

Custom airboxes prolly serve best in these applications

A pod filter would be the easiest to make a air box for but I'm pretty sure a large paper pod filter doesn't exist (I do want some filtering to happen that's why no oiled filter).
Anyone fitted a donaldson housing?
