Is it possible to use an OEM filter with an FIPK ? UPDATE - Yes it is !
UPDATE:
So I did purchase the FIPK kit, and I installed the AEM Dryflow 21-2057DK as recommended above.
After driving that setup for a few days I decided to tinker and see if the OEM filter would fit. What I found was that the OEM filter actually slips over the FIPK tube with about 1/16" extra clearance. As a temporary work around I wrapped the FIPK tube with duct tape until the OEM filter slid on snug and the tightened it with a hose clamp.
My impressions are that the OEM filter flows better than the DryFlow. It could be entirely placebo, but the car really seems to pull better with the paper filter.
What is not placebo is the difference in sound. The dryflow tends to muffle the sound a little, so it is less pronounced. The induction sound is definitely louder with the paper filter. It is a personal preference as to which sound is "better", but for my taste I very much like the sound with the OEM paper filter better.
I'm going to keep running the paper filter, but I probably need to figure out something better than duct tape to make it a snug fit.

That rubber seal works, get the one without the adhesive. I used some spray on Gorilla glue adhesive but you could probably do without that.
