How to clean cold air intake filter is a very important thing to learn as this component plays an important role by continuously supplying the engine with clean, cool air.

Clean Cold Air Intake Filter

The efficacy of the filter is diminished over time as a result of dirt, dust, and debris clogging it. To preserve the health and performance of the engine, it is crucial to routinely clean the cold air filter.

For this reason, we have provided a step-by-step guide for cleaning a cold air filter in this post.

How To Clean Your Car’s Cold Air Intake Filter?

To clean your car’s cold air intake filter, you need to identify the reason for cleaning, locate the cold air intake filter, remove it from the engine bay, clean it with a vacuum cleaner, clean it with a solution of dish detergent, or clean it with water.

1. Identify the Reason for Cleaning

Finding out why you need to clean the cold air filter is the first step in the process. Your car’s performance may suffer due to a filthy or blocked filter. It’s possible that you’ll see decreased fuel efficiency, slower acceleration, and possibly engine misfires.

Additionally, a clogged filter can lower engine power, resulting in a rough idle and worse performance in general. A drop in the engine’s power output is another indicator that your cold air filter requires a cleaning kit.

The engine’s power output declines when the filter becomes clogged because it limits airflow to the engine. Cleaning the cold air filter may be necessary if you notice that your car is having trouble accelerating or keeping up a consistent pace.

Last but not least, it’s important to check and clean the filter more regularly if you reside in a region with sandy or dusty circumstances. The dry filter’s ability to capture bigger debris and particles may be hampered by the accumulation of dust and sand on the surface.

2. Locate the Cold Air Intake Filter

You must first identify the cold air filter dry in your car before you can start cleaning it. It is crucial to consult your vehicle’s owner’s handbook to precisely find the filter because it can be found in different places depending on the make and model of your car.

Air Intake Filter

Most cars have rectangular or cylindrical housing beneath the hood that houses the cold air filter. Normally, the filter is situated between the car’s engine and the front grille. The filter may be fastened to the engine in certain situations using clips or screws and secured in others with a retention strap.

Once you’ve found the cold air filter, you might need to take a few things apart to get to it. For instance, in certain vehicles, you might have to take off the air duct that joins the throttle body to the filter housing.
In some situations, opening the filter housing cover may be necessary to reach the filter. It is significant to remember that some cars could have several cold air filters. In this situation, you will need to search for and clear each filter separately.

3. Remove It from the Engine Bay

The next step is to remove the cold air filter from the engine compartment once you’ve found it in your car. In order to prevent harming the filter or any other engine components, this step necessitates close attention.


Check the filter carefully for any signs of damage, such as fractures or rips, before removing it. If the filter is damaged, it should be changed rather than cleaned. Remove any clips, screws, or retaining straps that are holding the filter in place before attempting to remove it.

After that, carefully remove the filter from its housing. During this operation, take care not to drop any debris into the engine bay. Try gently wiggling the filter to free it from its housing if it is stuck or difficult to remove.
As employing too much power might harm the filter or other engine parts, avoid doing so. When removing the filter, it’s crucial to handle it gently to prevent damage. To further prevent damage, avoid using compressed air or high-pressure water to remove the filter.

Examine the cold air intake filter for any indications of damage or excessive wear once you’ve taken it out of the engine compartment. Go to the following step, cleaning the filter, if the filter is only filthy and not broken.

4. Clean It With a Vacuum Cleaner

There are various ways to clean the filter, but one of the simplest and most efficient ways is to use a vacuum. Start by lightly hitting the filter on a hard surface to get rid of any loose particles before cleaning it with a vacuum.

Cleaning Filter with Vacuum

After that, use your vacuum cleaner brush attachment to gently clean the filter. Be careful to thoroughly clean the filter on the inside and exterior. To prevent harming the filter, use mild pressure, and stay away from the sensitive or fragile sections of the filter when operating the vacuum air filter cleaner.

Use the lowest suction setting on your vacuum if it has one to prevent filter damage. To further prevent harm to the filter, avoid blowing it out with compressed air. Once the filter has been thoroughly cleaned with the vacuum, look inside to see if any dirt or debris is still there. In case there is still dirt, move on to the following step, which entails washing the filter with a dish detergent solution.

5. Clean It With a Solution of Dish Detergent

It is possible for tenacious dirt and grime to have collected on the cold air intake filter. Cleaning the filter with a dish detergent solution will get rid of this filth. As strong chemicals might harm the filter and decrease its efficacy, it is crucial to use a gentle detergent.

Solution of Dish Detergent

Start by adding a little amount of dish detergent to a container of warm water in order to prepare a dish detergent solution that will be used to clean the filter. The remedy should be well-blended. The filter should then be immersed in the solution, and any dirt or debris should be gently loosened by gently stirring it.

In order to guarantee that all the dirt is released, leave the filter for a few minutes to soak. After soaking, take the filter out of the solution and thoroughly rinse it under running water. Make sure to get rid of all the soap residue because it might impair the filter’s functionality. Before replacing the filter in the engine compartment, let it thoroughly dry off by air.

The filter should not be dried with compressed air or a heat source as this might result in damage. It is crucial to remember that the filter should only be cleaned with a dish detergent solution if it is extremely unclean or blocked. The filter may get damaged and lose its efficiency if it is over-cleaned.

6. Clean It With Water

The next step is to wash the cold air intake filter with water after cleaning it with a vacuum cleaner and a dish detergent solution. This step is essential to ensuring that the filter is properly cleaned of any soap, scum, and grime.

Using Water to Clean Filter

Use a mild stream of water to rinse the filter before cleaning it with water. Avoid applying too much pressure as this might harm the filter. Rinse the filter completely on both sides, being sure to get rid of any dirt or soap residue.

After that, lightly tap the filter to drain any extra water. The filter should not be twisted or wrung out as this might harm it. Instead, let it dry in the air. The filter must be dried after cleaning, which is a crucial step to remember.

By letting the filter completely dry, you may avoid the formation of annoying mold and mildew, which can harm the engine and lessen the filter’s efficiency. Place the filter somewhere clean and dry so that it may finish drying by air alone. The filter should not be dried with heat or compressed air as this might harm it.

Can Cleaning the Cold Air Intake Filter Fix White Smoke From the Exhaust on Startup?

Cleaning the cold air intake filter can indeed be one of the white smoke exhaust startup fixes. As the filter becomes clogged with dirt and debris over time, it restricts airflow, causing a rich fuel mixture. This excess fuel can result in white smoke during startup. Regularly cleaning the filter ensures proper airflow and may aid in resolving this issue.


Now that you have learned about how to clean a cold air intake filter, you can guarantee your vehicle operates as efficiently and effectively as possible.

To summarize the main ideas that we have discussed here:

  • A filthy cold air intake filter can have a severe effect on the performance of your automobile’s fuel economy.
  • Before starting the filter cleaning procedure, it’s critical to determine why the filter has to be cleaned.
  • Find the cold air intake filter in your car’s engine bay, then pull it out.
  • Utilizing a vacuum cleaner, water, and dish detergent solution, thoroughly clean the filter before letting it air dry.
