I have the DDM intake on my car, but I don't know what the "gray foam" part is you are speaking of.

Hi jbewley
The filtering system is made in 2 parts ,the outside the part we see in red can be remove, under you have a grey foam with a spring inside,these are seperate parts.Hope that answers to your question -
I think you have a different filter with yours. Mine came with a regular, one piece K&N cone filter.
On the Way Motor Works web site, they show one like you are describing called a duel foam filter and it is on an R50. Drop Way a PM and I'm sure he can help you out.
