Have you ever seen a supercar before? Their aggressive styling usually includes massive vents either on the hood of the car, at the flanks of the front bumper or most commonly, around the rear tire arcs. Believe it or not, these structures serve more than an aesthetic function. They provide the car's engine with the oxygen it requires to burn fuel and generate the energy that propels the vehicle. These vents are known as air intakes and happen to be a common feature across all combustion engines.
