Like I said, ceramic coating can do so much to defect ambient heat away from piping, core, etc. About the incab stuff: there comes a point that doing something more radical just doesn't really net any benefit if the original setup is done properly in the first place. With a proper setup, there should be very little theoretical performance gain between in and out of the engine bay. You can't prevent having charge air piping in the engine bay, no matter where the intercooler core actually is, so ceramic coat it and call it a day. We're seeing almost 40% less radiated heat from our exhaust header (race car) after getting it ceramic coated, and roughly the same should apply for keeping heat out of charge piping. The amount of cooling power in the core vs. the amount of radiant heat it absorbs from the engine bay is small compared to the heat that the core has to dissipate from the charge air, so that's not too much of an issue either.
I think in cab stuff is cool (and convenient) for race setups, but I'm not willing to sacrifice interior room for such a small performance gain that can be gained from doing some other thing instead.
