im no expert but if you were to paint the intercooler wouldnt it clog the holes not allowing as much air through the intercooler to cool down the air u want cooled... and as for tinting windows the tint actually reflects the heat and doesnt allow it to come through...if you were to look in a car with tint the light that does come in isnt as bright because it isnt letting as much light in as if there were no tint.... hope that helped
