K&N air filters are a popular choice among car enthusiasts due to their ability to increase horsepower and acceleration while providing excellent filtration.
However, like any air filter, it needs to be cleaned and maintained to ensure it is working at its best. In this article, we will explain the steps on how to clean a K&N air filter without a kit.
How To Clean A K&N Air Filter Without Kit
While K&N does offer air filter cleaning kits, it is possible to clean your air filter without using one. Here’s how:
- First, remove the air filter from your car. Consult your owner’s manual if you are unsure of how to do this.
- Once the air filter is removed, tap it gently on a hard surface to remove any excess dirt and debris.
- Next, hold the air filter under running water, making sure to rinse both sides. Use a gentle stream of water rather than a powerful jet, as this could damage the filter.
- Once the filter is thoroughly rinsed, allow it to air dry completely. This can take several hours, so be patient. You can speed up the drying process by using a fan or blowing air onto the filter with a hair dryer set to the cool setting.
- Once the filter is dry, use a soft brush, such as an old toothbrush, to remove any remaining dirt or debris. Be sure to brush gently to avoid damaging the filter.
- If your air filter is particularly dirty or if you want to remove any remaining oil from the filter, you can use a mild soap solution. Simply mix a small amount of dish soap with water, apply the solution to the filter, and rinse thoroughly.
- After cleaning the filter, it is important to re-oil it to ensure it is working at its best. K&N recommends using their filter oil, which is specifically designed for their filters. Follow the instructions on the oil to apply it to the filter.
- Once the filter is clean and oiled, it is ready to be re-installed in your car. Make sure it is seated properly and securely before closing the air filter housing.
By following these steps, you can effectively clean your K&N air filter without the need for a kit.
What Else Can You Use To Clean A K&N Air Filter?
In addition to using water and a mild soap solution to clean a K&N air filter, you can also use a specialized air filter cleaner.
These cleaners are specifically designed to loosen and remove dirt, grime, and oil from air filters without damaging the filter material.
Some brands of air filter cleaners include K&N’s own air filter cleaner, as well as other popular options such as Red Line and Maxima.
To use an air filter cleaner, simply follow these instructions:
- In general, you will want to apply the cleaner to the filter and allow it to penetrate and loosen any dirt or debris for a period of time, usually around 15-30 minutes.
- Then, use a soft brush, such as an old toothbrush, to scrub the filter and remove the dirt. Rinse the filter thoroughly with water and allow it to air dry completely before re-oiling it and re-installing it in your car.
- It is important to note that not all air filter cleaners are compatible with all types of air filters. Be sure to read the label and use a cleaner that is specifically designed for use on your particular type of air filter.

Can You Use Soap And Water On A K&N Air Filter?
Yes, it is safe to use a mild soap solution to clean a K&N air filter.
K&N recommends using its own air filter cleaner, but if this is not available, a mild soap solution can be used as an alternative.
To make a soap solution, mix a small amount of dish soap with water.
Apply the solution to the filter and use a soft brush, such as an old toothbrush, to gently scrub the filter to remove dirt and debris.
Rinse the filter thoroughly with water to remove any soap residue, then allow it to air dry completely before re-oiling it and re-installing it in your car.
It is important to use mild soap and to rinse the filter thoroughly to avoid damaging the filter material.
Strong or harsh cleaners, such as solvents or degreasers, should not be used on an air filter as they can damage the filter and affect its performance.
What Is The Best Way To Let A K&N Air Filter Dry After Cleaning?
The best way to allow a K&N air filter to dry after cleaning is to let it air dry completely.
This can take several hours, so be patient. To speed up the drying process, you can use a fan to blow air onto the filter or use a hair dryer set to the cool setting to blow air onto the filter.
Avoid using heat sources, such as a radiator or stove, to dry the air filter as this can cause the filter material to become damaged or shrink.
Additionally, do not use compressed air to dry the filter as this can force water and dirt into the filter material, which can cause it to become damaged.
Once the filter is completely dry, use a soft brush, such as an old toothbrush, to remove any remaining dirt or debris.
Then, follow the instructions on your K&N filter oil to apply it to the filter before re-installing it in your car.
What Can You Use To Oil A K&N Air Filter?
K&N recommends using their own filter oil to oil their air filters.
This oil is specifically designed to work with their filters and helps to ensure optimal performance.
To use the oil, follow these instructions:
- In general, you will want to apply a thin, even coat of oil to both sides of the filter, taking care to saturate the filter material.
- Be sure to shake the oil well before using it and avoid using too much, as this can cause the filter to become over-oiled and affect its performance.
If you do not have K&N filter oil, you can use another brand of air filter oil that is compatible with your particular type of filter.
After applying the oil, allow it to penetrate the filter material for a few minutes before re-installing the filter in your car. This will help the oil to fully saturate the filter and provide optimal performance.
Do You Have To Oil A K&N Air Filter After Cleaning?
Yes, it is recommended to oil a K&N air filter after cleaning it to ensure it is working at its best.
The oil helps to protect the filter material and improve its performance by trapping dirt and debris and allowing air to flow through the filter more easily.
Can A Dirty Air Filter Be Re-used?
A dirty air filter can technically be re-used, but it is not recommended.
An air filter’s primary function is to protect your engine by trapping dirt, debris, and other contaminants before they can enter the engine.
When an air filter becomes dirty, it becomes less effective at trapping these contaminants and can even allow them to pass through the filter and enter the engine, which can cause engine damage and reduced performance.
For these reasons, it is generally recommended to replace a dirty air filter rather than attempting to clean and re-use it.
Depending on your driving conditions and the type of air filter you have, it may be necessary to replace your air filter every 15,000 to 50,000 miles or more frequently if it becomes excessively dirty.
Consult your owner’s manual or the manufacturer’s recommendations for specific guidance on how often to replace your air filter.
Cleaning A K&N Air Filter
In conclusion, cleaning and maintaining your K&N air filter is an important step in keeping your car running smoothly.
By following the steps outlined in this article, you can effectively clean your air filter without the need for a specialized cleaning kit.
Regular cleaning and maintenance of your air filter is important to ensure it is working at its best, which in turn will help extend the life of your engine and improve the performance of your car.
Remember to use a mild soap solution or specialized air filter cleaner, and to oil the filter after cleaning to ensure it is fully protected and functioning at its best.
Proper care of your K&N air filter will help ensure it continues to provide excellent filtration and performance for the life of your car.
