Heat in the intake is something I'm trying to address. I upgraded the heat exchanger
in the passenger's side and added an intake port to allow more air in. I also
added a second heat exchanger to the driver's side. Here are a few photos:

I increased the air intake to the intercooler heat exchangers to 4".

Here is the difference in the hose that feeds the shroud at the heat exchanger:

I also opened up the exit port:

(Drivers side)

(Passenger side)
I think a better place to exit the air is through the top of the fender. I'm thinking about
adding some slots/gills up there...
