Yea, I am looking for the cold air. I have been thinking about the needswings but having a custom setup would be really cool.

I looked again today, and noticed that there is a water hose coming straight out the front of the engine just under the air injection. Looking at the location of the throttle body at the back I am not sure its going to be possible...

Maybe a custom manifold could work, however I would loose the functionality of the different length intake horns in the stock manifold...
