Air Filter Housing

What is an air filter box and where is it located?

The air cleaner housing assembly (also commonly referred to as an air box or air filter housing) houses and protects the air filter from the various harsh elements that could potentially weaken and damage it. This allows the air filter to do its job of filtering out any impurities in the air before it flows into the engine. The air box can usually be found near the front of the fender, inside the engine compartment. A typical air filter housing will have an air inlet on one side of the filter to allow in the fresh air and an outlet on the other side of the box that goes to the air intake hose leading to the throttle body on the engine. Some air filter boxes may also have baffles inside to quiet engine noise, air intake temperature sensors, or mass air flow sensors.

When do I need to replace my air cleaner housing?

The air cleaner housing assembly is not a part that requires regular maintenance or replacement. However, since it is made of plastic, it can crack from pressure or extreme environmental conditions.  Sometimes air boxes can break when changing the filter. This can happen when the person performing the maintenance does not know where all the bolts are or exactly how the box comes apart, so they may try to force it open, effectively breaking the box. Improper installation may also lead to broken closure clips or stripped screw holes, as well as to over-tightened mounting bolts that can cause the area around them to break. Lastly, due to its location in the engine bay, they are often broken when the vehicle is in an accident.

Replacing an air filter housing

Replacing the air filter housing is generally an easy and straight forward job. Make sure to remove and transfer any sensors located in the old box into the new one. Disconnect the engine inlet air hose on the outlet of the housing. Remove the air filter and check for any damage or contaminants, and replace if necessary. Remove any mounting hardware, and the housing should be free to pull out.

Breaks and cracks in the air box can disrupt the air flow, which can lead to rough running and poor fuel economy. A broken air box can also allow unwanted dirt and contaminants to enter into your vehicle’s engine. This can foul your mass air flow sensor, which is an expensive repair and/or prematurely wear out your engine, which is an even more costly repair. Therefore, if your vehicle’s air cleaner housing assembly needs to be replaced, it is imperative that you do so as soon as possible.
