Your car's hood vent has a dual function: first, it provides proper ventilation for your engine. Second, it serves as a decorative statement to distinguish your car from others running on the road. There is not much fuss about which type of hood vent a specific model of car should sport. The choice is actually upon the driver himself-he must choose a hood vent that both functions as a heat relief for the engine and as an identifying feature of his car. If you are looking to buy new vents for your to-be-customized hood, then here are the tips that will help you pick the best ones.
Which type to choose?
There are five types of car hood vents: air extractor, bulged, cowl induction, louvered, and ram air. The bulged hood is the simplest one, which is similar to those used in the Mitsubishi Eclipse Turbo. It may have one, long, forward-facing vent or a smaller one enough to keep incoming air to cool the engine. Buy this one if you have a huge engine to conceal that cannot be hidden with a flatter hood.
The air extractor hood vent has downward-facing louvers that accommodate more air for cooling the engine. Buy this hood if you want more high-pressure air to escape from the engine compartment, thus resulting to a better engine performance.
The louver type is basically a design and is appropriate for cars that do not usually overheat. This type has short or long slits arranged in rows.
If you want more air going into your hood, then opt for a ram air vent. This type has a forward-facing air scoop that may be a pop-out or recess type. The function of this vent is to allow more high-speed air to enter and then escape the hood. If you are a racer, this type is appropriate for your car; however, the vent may produce aerodynamic drag.
The cowl induction scoop uses a backward-facing vent to catch air hitting the windshield. Buy this one if you want the benefits of a ram air type without the aerodynamic drag.
What are other things to keep in mind?
Make sure that the hood vent you are going to buy is appropriate for the make and model of your car. If you want to save money, you may also have your own hood customized to accommodate a vent. Vents are also made from the same material used in hoods, but some modern ones are from aluminum and carbon fiber. Buy lightweight and easy-to-install ones to prevent any fitting hassle. Hood vent prices are just reasonable, but some qualities like UV protection and high-gloss or matte finishes may increase the cost.
