You can buy a WRX hood scoop off of eBay, and install in in the hood, right above the filter, then build a box, around the cone, to block off heat from the engine.
This would be truely cold air induction, and water, and everything else.
I have the K&N kit on my car, and I like the roar. I have 2 filters. I oil one, and let it sit for a month or so, then install it on the car. It still gunks up the MAF, and I have to clean it all the time.
I do not worry about trash, or dust particles, or getting anything in the motor, because the K&N filter does a great job of cleaning the air. It just has a lot more surface area, and can allow the motor to suck more air in.
The oil does "activate" the fibers, to get even more "stuff" out of the air.
My wife thinks the car is going to explode, if I ever get over 5500 RPM, from the scream from under the hood. The stock filter box really made the engine quiet.
