love that cooler air!!!!

my IAT's are really close to ambient lately, after sustained highway driving.

airflow rate is another story, but i don't think you're losing much (if any) power on the stock airbox, compared to some intakes (BMW performance, for one). i also think the true long-tube CAI like Dinan's carbon fibre one is a decent choice. ultimately, for me, i'm keeping my intake stock. i have catless headers and a custom flash tune; no need to milk an extra few HP in exchange for a louder induction noise or a CAI that could potentially injest some water. had a CAI on some previous cars.....had some hydrolock scares because of stupid houston roads and how much it rains here. /csb
