I have a much better and cheaper idea. Cool the intake with liquid nitrogen. A 15 gallon dewar in the trunk would stay liquid for weeks when not in use. you could build a box shaped section of the intake. The LN2 would flow through pipes around the compressor discharge absorbing the heat. That would turn it into a gas. The super cold gas would flow through hollow plates in the box shaped chamber chilling the air even more. The still quite cold gas could then be used to help cool the turbine housing or the intake manifold. The box part would have to be heated up once in a while to keep ice down.
