well in the end it's a non-issue for me (mostly) living in So. Cal but who knows, what can happen. how about we come to the consensus that if you're driving with a CAI in a rainy place and don't have a bypass valve, that you might want to reinstall the stock airbox for whatever seasons in which the rain comes fiercest.
