But here is the point, how much more can it be in the BOM of a car to have an aluminum intake, not very much. I like Detroit iron, I just hate seeing the bean counters have such an impact on components because you know the engineers don't like it.
Sometimes cars get plastic intakes for reasons other than being cheap.
Having low intake air temperatures is a must for good engine performance, and plastic transfers less heat to the intake than aluminum does.
