At the top, there’s a valve called the choke that regulates how much air can flow in. If the choke is closed, less air flows down through the pipe and the venturi sucks in more fuel, so the engine gets a fuel-rich mixture.
Why is the firing order not 1234?
In engines, cylinders don’t fire in the sequence of 1-2-3-4-5-6 and so on as it could cause the crankshaft to deform or break. So, manufacturers shuffle the combustion in such a way that it creates power balance in the engine.
What do Shaker Hoods do?
Since it is fastened directly to the engine, it moves with the engine’s movement and vibration on its mountings, thus the ‘shaker’ name. … Other benefits of a shaker hood include elevation to prevent water from being drawn on flooded terrain, a cooler source of air, and a more direct path to the engine’s throttle plate.

In the picture you have shown it is an air intake. It is outside the hood so that air is taken from outside the engine bay. This is because the air outside the engine bay is cooler and hence is denser which is better for combustion. Most of the times it’s the air intakes that stick out of the hood.
