I built mine for function, the blower is working to get more air in, I am working to make that process as efficient as possible, then looking to do a heat exchanger for it to cool it, now I still need to build a box around the intake but it is worth while to allow the engine to breathe as much as possible. I ordere a 45 degree silicone elbow, a 4" piece of 4" diameter airaid intake tube and a K&n filter then put the IAT in the 45 degree elbow. It is not pretty but it works.
