Is there anyone out there who would discourage me from fabricating my own intake?

If not, who would want to buy my AEM cai with no filter when I'm done?

IMO you do what you want. How much for the leftovers?

I wouldn't discourage, I would encourage it. In fact, I'm planning one myself. It involves bringing the inlet up to my "now functional" grill and creating a ram air effect. The intake will be sealed against the grill with baffles in blace to help keep the water out. We'll see if it works.

What are your plans, if you don't mind me asking?

Well I'd like to just make a short bent pipe to mount behind the fog light, or just under the headlight. The more straight the better I'm thinking, and there's the possibility of using a flexible pipe.
I'd also make some internal fenders to block the water due to the lack of the bypass currently on my AEM.
The reason I posted this is because I was curious if I should be putting much stock in the supposed 'tuning' of the aftermarket intakes for the turbulence problems that might arise. My thought is that if the intake diameter matches the manifold's intake diameter, it shouldn't matter much if at all.
I admit that I'm just a bicycle mechanic, not an auto mechanic, so any advice or insight would be greatly apreciated.

For the AEM I'll have to see if I use the filter or not, and if my friend might use it, but I can't see asking more than $100- for it. I'll let you know if it's available.

By the way rollotomassi, what you're doing sound great. With the aerodynamics of these cars, or lack there of, it sounds like your design will work well on the highways. Which is the reason I'm doing what I'm doing. The shorter intakes benefit more at the high rpm's and I do a lot of road-tripping.
