Its been a while since I've done anything like this, but pod filters on their own, while sounding great, suffer badly from heat soak and ultimately will decrease your performance noticably.
If you can't get a stock airbox, search on these forums for making your own CAI (Cold Air Intake) with an insulated foam box and pipe. Then you can just put a well functioning pod on (K&N). Theres lots of options here with some folks raving about pod filters under the headlights (in the vent) but they get wet easily. Its up to you how far to go.
