What are our options for a 4" replacement filter?
I have the T1R intake and it looks like the element is becoming a little dirty and I'm seeing a little wear-thru on the wire mesh. (I bought the intake second hand)

I've always been a big fan of Apexi's filters and their ability to maintain high flow while still acting as a filter.

I just can't find an inlet opening bigger than 3"

Anyone have any ideas?

(I'd prefer an dry intake over an oiled cotton gauze)
