I'd like a CAI but it might be more of a hassle than it's worth. In Houston, it's hot and humid 90% of the time and the rest of the time it floods. I don't want to worry about hydrolocking my engine. I figure I have less chance of that if I just modify my stock box. I dunno. I saw some cold air boxes around a short ram intake on the weapon-r site (www.weapon-r.com/airbox.html) and Sport Compact Car says "Underhood temperatures can easily exceed 160 degrees Farenheit so do everything possible to ensure you draw the coolest air avaliable into your engine. Build a wall out of ABS plastic, aluminum, or even rubber sheeting that isolates the filter from the rest of the hot engine compartment."
I might try to fabricate one if I get some free time later this year... i'll see.
I'm also looking at upgrading the fan like you said.... but they're $$$. What about trimming some of the bodywork to promote airflow... :wink:
