The power gained by this method can vary depending on how restrictive the factory air box is. The most basic cold air intake replaces the stock air box with a short metal or plastic tube leading to a conical air filter, called a short ram air intake. Because cooler air has a higher density (greater mass per unit volume), cold air intakes generally work by introducing cooler air from outside the hot engine bay.

The intake snorkel, or the opening for the intake air to enter the system, must be large enough to ensure sufficient air is available to the engine under all conditions from idle to full throttle.Ĭold air intakes operate on the principle of increasing the amount of oxygen available for combustion with fuel. The most efficient intake systems utilise an air box which is sized to complement the engine and will extend the power band of the engine. The two more common types of mass airflow sensors are the vane meter and the hot wireĪ cold air intake is used to bring cooler air into a car's engine, to increase engine power and efficiency. The electrical resistance of the wire increases as the wire's temperature increases, which limits electrical current flowing through the circuit. When air flows past the wire, it cools, decreasing its resistance, which in turn allows more current to flow through the circuit.

The hot wire uses a series of wires strung in the air stream. There is also a second vane behind the main one that fits into a closed camber that dampens the movement of the vane giving a more accurate measurement. The more air coming in, the more the flap is pushed backed. The vane type has a flap that is pushed by the incoming air. They are the vane meter and the hot wire. There are two common types of mass airflow sensors in use on automotive engines. From mass flow sensor, then, does it goes to the throttle body. It is found in a compartment in an air duct to the throttle valve assembly under the hood of your car.Ī mass air flow sensor is used to find out the mass of air entering a fuel-injected internal combustion engine. The air filter is usually located in the air stream to your throttle valve assembly and intake manifold. The air filter prevents dirt and other foreign particles in the air from entering the system A good air intake system allows for clean and continuous airflow into the engine, thereby achieving more power and better mileage for your car. Oxygen in the air is one of the necessary ingredients for the engine combustion process. The function of the air intake system is to allow air to reach your car engine.

So the question is - what exactly do we need to know about it? Now that modern engines are not equipped with carburettors, it's the fuel-injected engines we are concerned about.

The tubes are typically powder-coated or painted to match a vehicle. Now, with the technological advancement and ingenious engineering minds, intake systems are available in metal tube designs, allowing a greater degree of customisation.

In the 1980s, the first air intake systems were offered and consisted of moulded plastic intake tubes and a cone-shaped cotton gauze air filter.Ī decade later, overseas manufacturers began importing popular Japanese air intake system designs for the sport compact market. There are a handful of car owners out there that are not quite sure what an air intake system does, how it works or how important it is to a car.
