I can't remember who first did it, but I have a small 2" gauge pod and an AC vent installed under the driver side splash-guard (misplaced my supplies so I haven't done the passenger side yet), but I still get a significant amount of hot air in the cockpit. I've been thinking about trying an intake hose thru the top holes in the splash-guard, but just haven't gotten around to it.
Number of different ways to get air in...sometimes it's good for those who have been around a little to share some of this stuff so the new guys can get a clue.
