Actually....
You want the air intake to be cool...
Engine temps must be hot enough to burn correctly.
If you reduce your intake temps thats all you need to do.
You can do the rear vent thing like RCI did, Pipe in some air from the front airdam and enclose your air filter with a heat shield. those will all help.
i been running my DMS without the front bumper since i installed the new FMIC and there is a huge difference in the temps. the intercooler is working great
