Cooler intake manifold

..are you just driving your car on the street? A bit of manifold heat will atomize the fuel better, may improve mileage and burn cleaner.


BINGO. If you are going to run a cold manifold you need to understand what happens if you don’t get the fuel atomized well enough leaving the booster. If the manifold is too cold, you’ll lose power and burn a bunch more fuel if you don’t the fuel atomized at the booster.
