Let me know how you get on with this. I wanted to design a duct which allows the filter to be closer to the front grill (on a mk1) to allow it to get to the cooler air. I understand it can be dangerous driving in water like this but I wouldnt be daft enough to go driving through big puddles. This would be an open cone set up.
Another option would be to mimic the design of a DIA (made by bcm). Have a short duct from the throttle body/afm sensory to a closed filter and direct some piping to the lower section. This would allow the filter to be placed right into the engine bay. Probably gain better torque this way being an enclose filter.
I have currently just got a K&N pannel filter and am going to drill my airbox for noise.
