For years with carb vehicles a heated air cleaner was used to vaporize the fuel, fuel droplets do not burn very well. Had two air intakes, one from under the hood, other piped from a fitting on the exhaust manifold with a thermostatic controlled valve to chose between the two to get 160*F heat. If the tube running to the exhaust fitting, the engine would run like crap.
Intake manifold doesn't need preheat, already preheated by the engine as the fuel injectors spray directly into it. For more intake air, the turbo handles this function,up to 35 PSI peak. If you play around with this from OE, more than likely will get poorer performance.
Actually feel an aluminum intake manifold would be superior to plastic, would conduct engine heat far better, but what can you say about plastic, far cheaper to manufacturer.
But gather it so expensive because you just can't buy the manifold, comes with injectors, TB, and other stuff.
Over 310 bucks.
Ha, if you want cold air, come to Wisconsin, like 30 below, not only get winter gas, but that cold air doesn't vaporize the fuel very well.
