I hadn't thought about the pressurized ram air box deal. How much of a pita are they to set up and tune?
I called airtech a few days ago and they have two kits. The FIM which is the one they recommend for street use and the AMA. The AMA kit has three ram air ports, the two stock ones and an extra one that goes under the steering head above the radiator. The AMA kit also comes with straight through ram air tubes which the FIM kit does not. Other that that the two kits are identical. They also cost the same ~$500 US
They both come with some weather strip material that clips the upper and lower half of the airbox together (no tools needed to remove :clap) and the only thing you'd have to do is drill the holes to mount the air box to the cylinder head. The AMA kit would require some work work to get it to fit right. Also neither kit comes with anything in terms of an air filter. You'll either have to fabricate your own screen or use pod filters.
The guy I spoke with on the phone said that the FIM kit MUST be used with the stock ram air tubes but I don't think he quite knew what he was talking about. I'm sure if you got straight-thru tubes from somewhere they'd work.
Airtech offers both kits in fiberglass as standard. For double the money, you can have it made it carbon fiber.
