Just how important is air to your vehicle's engine system? Air is what helps the engine burn fuel and convert its chemical energy into more useful mechanical energy. Air is also vital in the engine cooling process; cool air is helpful in picking up and dissipating engine heat from the radiator. So the higher the amount of air intake is, the more efficient your vehicle's engine is. And one of the ways you can increase your vehicle's air intake is through the hood scoop. The hood scoop is designed to be mounted on the hood, on top of the engine bay. From this position, the hood scoop draws in cooler, denser air into the engine compartment. With the increased air intake, the engine's power output is bound to increase as well. You can think of it this way: air from the grille will go directly to the intake system while air from the hood scoop goes to the engine bay. On top of that, a hood scoop can make your ride look sportier!
• Aids the cooling process by hoarding in more air via an opening on the hood
• Concentrates airflow in the engine bay
• Additional aesthetic accessory for your vehicle
How to Choose the Right Type of Hood Scoop
There is more to a hood scoop than just mere design and style in your car. Those dents, holes, and bulges are actually functioning as "breathers." They also help in maximizing the potential of combustion chambers to burn fuel. Cold air makes oil thicker, which allows the engine to squeeze more energy from it.
Given these benefits of hood scoops, you should pay attention to the functionality of the design and type when selecting which one to buy and install in your car. There are several types of hood scoops and each has its unique characteristics and special benefits.
Types and functions of hood scoops
- Louvered hood scoop- A louvered scoop is easy to recognize. They look like gills of a fish. Surprisingly, they both work the same way; they are inlets and outlets of air. This application is great for those who have low-suspension cars because the scoops are not protruding and they do not block the driver's view of the road. It is also appropriate for cars which have the tendency to overheat fast because this type's design consist of several holes, thus it permits more cool air. This is commonly used in Ford Mustangs, Hummers, and Honda Civic.
- Air extractor scoop- Looks the same as louvered though it is smaller. Its main function is to serve as vents to release heat from the engine. If you're finding the best solution for overheating, this is the right choice. This is also easier to install than the louvered type.
- Ram air scoop- This scoop was popularized by race cars. If you own one, this can work well. It is designed to catch enormous amounts of air that is produced from driving extremely fast. Since this is always exposed to heavy air pressure, make sure to choose the one that is made of fiberglass because they are stronger against the wind than plastics.
- Cowl induction scoop- Both this type and the ram air scoop share the same mechanism. This type though is bigger in appearance. It actually looks like a huge bulge on your car's hood. That design is made strategically to absorb high-pressurized wind that often strikes the windshield, grilles, and bumper. Among all the other types, this is the best when it comes to engine cooling and fuel efficiency. However, its design is the least desirable. Perhaps it's made to improve performance and not style.
Other useful tips:
- Have your air filter checked regularly. A hood scoop allows the entry of dirt and debris so you need to add extra maintenance.
- Choose a hood scoop that can withstand extreme weather conditions, heat, corrosion, and wind. Choose scoops that are made of durable ABS materials, fiberglass, and aluminum.
Ready, Set, Scoop: How to Install a Hood Scoop in Your Car
There is so much more to a hood scoop than the style it brings to your car. The truth is, it is created for mechanical and not for aesthetic purpose. It functions as an entry passage for cool air to flow directly to the engine compartment. It provides cooler air to lessen the heat around the engine. It is also one of the best race-car performance enhancements. The hood scoops in race cars uses the high levels of pressure produced by the car's extreme speed. The pressurized air inside the engine doubles the cooling effect. So whether it's for function or style, installing a hood scoop is a good addition to your car. Now if you're planning to install it all by yourself, you need to prepare a few very important tools and pieces of equipment and be familiar with the following steps.
Difficulty level: Difficult
Tools you need:
- Grinder with cutting wheel
- Hood scoop of your choice
- Zeus clips
- Permanent marker
- Tape measure
- Sabre saw
- Sand paper
Step 1: Protect yourself. Wear your safety glasses, gloves, and work clothes. You'll be using drills and other sharp tools so wear safety gears to avoid any accident.
Step 2: Take the hood out of your car. Once it's out, use a sandpaper to scrape the paint on the area where you're planning to install the scoop so that the temporary markings you'll make don't smudge away.
Step 3: Now that the hood is out, take a look inside the engine and locate the car's carburetor. Scoops are best placed directly on top of the carburetors for enhanced performance. Mark or measure its location before going back to the hood.
Step 4: Copy the same measurement on the car's hood then proceed with the cutting. Check the shape of the end of the scoop you are about to install. Use a marker to plot it on top of the hood. Once you're ready, cut out the shape using a sabre saw.
Step 5: Cut out the holes on the scoop and on the hood where you can insert the bolts to hold the scoop in place. Use the sandpaper to smoothen the edges.
Step 6: Attach the scoop. Tighten the bolts and screws to keep the scoop steady and firm. Once you're finished installing the scoop, you can put the hood back in the car. If you have plenty of time, you can repaint the scraped part of the hood.
Be amazed with your car's new look. The time duration of the installation varies depending on the DIYer's skills. Follow these instructions and you'll do well.
