K&N makes that sock for the air filter to prevent water infiltration. Shouldn't be an issue.
Too bad gen 1's can't do turbos... (stupid air assisted injectors).
I wonder if we can swap a gen 2 intake mani/fuel rail to make it work...
I didn't know k&n made one, but I do have one from when I tried running the filter down to the bumper. I know it prevents water from getting in but thats just asking for trouble, even with the sock. Last winter I had to drive through about 3 feet of water since to get out of school and I even thought my filter would suck in water being in the engine bay, now imaging it being in the bottom of the car
