Nice plate and x2 on the prefilter. It actually makes it look cooler too - they have a few color choices. The prefilter will also catch any minor water that may enter after a carwash. I am running the K&N CAI now with a prefilter, but if I recall, when I had the Airaid, I got the prefilter from autoanything.com. At the time, they were hard to find - maybe easier now???
