Where is the air filter located?

Published on : 31 October 20192 min reading time

Just as the lung allows humans to breathe and live, the air filter plays the same role in the operation of a vehicle’s engine. Unfortunately, some drivers still don’t know where the air filter is in a car even though they have a nice machine. This famous place depends on the model of the car and the type of engine. Here is a quick overview of the different possibilities to learn how to quickly find the location of this accessory.

For older vehicle models

Originally, older vehicles ran on gasoline and were powered by a carburetor. For operation requiring a mixture of air and fuel to promote combustion, air quality must always be optimal to avoid malfunctions and breakdowns resulting from poor quality mixing. For these older vehicle models, the air filter is therefore placed directly above the carburettor. Usually, they are placed inside a plastic housing, which is immediately attached to the carburetor. If you are looking for the location of the air filter in a pre-1990 car, then you only need to look for the box that contains it.

For new generation models

In the late 80s and early 90s, the housing was a little out of place compared to the carburettor, out of concern for space and also to maintain a correct appearance. A pipe connects the housing containing the air filter to the carburettor. But with the advent of the injection engine, a new air filter model was introduced with the application of the so-called direct intake system. To find out where the air filter is in a car equipped with these injection engines, simply look for an object placed upstream of the intake pipe connected to the flow meter and injectors. This is the air filter. Flat, rectangular or conical for high performance vehicles, it now comes in several shapes and no longer necessarily requires the presence of the box containing it.

Special case

For certain types of vehicles, such as off-road vehicles and trucks, an additional protection system called snorkel accompanies the system integrating the air filter. To find out where the air filter is in a car of this type, simply follow the hose from the outside to the inside of the engine compartment and you will find it.
