Air intake to the bonnet - to whom the lining, to whom the effective ventilation and cooling system

In racing cars, all aerodynamic body kits are of great practical importance. They are not a tribute to fashion or the desire to strengthen the aesthetic effect, but serve certain purposes. For example, an installed air intake on the hood during a rally directs a stream of cold air to an engine operating in an enhanced mode, which provides its additional cooling.

During motor racing it is unacceptable to open windows, because the car body must have good aerodynamic characteristics. At the same time, the engine compartment is as good as hot heating appliances, it spreads heat, heating the interior. In order for the pilot not to overheat, set the air intake on the hood so that he began to form air flows and distribute it in the right directions, creating a ventilated space.

A lining made by one's own hands or bought in a store

Since each driver of the car in his heart is always a driver, many people began to make a decorative air intake on the hood with their own hands, to give the car a sporting style and stand out from the crowd. To do this, some simply applied a foam to the sheet of film . From it, and formed a decorative element.

Very carefully, so that the foam does not touch the paint, it was applied to the film spread out. When it hardened, they took a knife and created from this mass an element similar to the air intake mounted on the race car. On the hood it was attached after the pasting of the form with fiberglass, dried, cut out the slits, covered them with a net and painted in the right color. As a fastening material used rivets or sealant.

Today, if you do not want to mess around with foam and paints, you can buy a ready-made overlay that represents the air intake. On the hood, it will be installed reliably, so the first wind flow will not break it.

Air intake for better engine cooling and ventilation

There is another category of motorists who are not very interested in decorative qualities, but are focused on practicality. These include those who live in the southern latitudes or make long-term non-stop travel and are therefore interested in enhancing the cooling capabilities of the engine and in the ventilation of the car's interior. Many of them - craftsmen of all trades, they will easily find schemes, learn the operation of such a system and make an excellent air intake on the hood.

Others will order it in a specialized auto repair shop where professionals will make a full calculation of the system, according to which the air flows will be directed with a certain force to the place of the engine compartment where the temperature is much higher at high engine loads. Also, experts will distribute flows in the right directions and ensure maximum design efficiency. If necessary, they will install not one, but two air intakes, connect to them ventilation systems, made by engineering calculations.
