Step 1: Take Out The Filters

Then you will want to rotate the filter and aerosol spray it again to get rid of any dust that has accumulated around it. Once you have washed it well, let it out for 10 to 15 minutes anywhere near the sink to dry entirely.

Step 3: Washing

The filter will need to be washed with water in step three. However, for a proper wash, you’ll need to follow the specific methods. 

Initially, you should look at where the airflow enters the K&N filter. Turn that side to the faucet and run it with water as soon as you find it. It’s best if the water is a little warm.

However, it should not be excessively hot or too cold. When you start pouring water, you will notice stuck specks of dirt coming out of the interior. Then connect the other end of the filter to the faucet and let the water run once again. However, for faster cleaning, you may use a nozzle with more pressurized water.

Step 4: Shake and Dry

After you have finished washing it, you must dry it as swiftly as possible. You should shake the filter a few times at first by grasping the filter’s outer layer. Then store it somewhere safe to dry for 20 minutes.

Step 5: Oiling

It’s time to let the K&N oil spray finish the job. After the filter has dried, remove it with one hand while using the other to spray. Slowly spray the oil on both sides of the filter in single areas.

Step 6: Clean it off

After 5-6 minutes of oil spraying, clean the interior of the filter with a cloth with your index and thumb fingertips. When you’ve finished cleaning it, you may reinstall it to its original location.
