K&N Oil Filter Review

K&N air filters are composed of layers of cotton gauze tucked in between sheets of aluminum wire mesh. This cotton technology generates a robust filtering medium by retaining oil in suspension on the cotton material. The K&N filter oil suspension allows the air filter to trap and hold dust particles that are much smaller than the opening in the fiber itself.

Step 1: Take out the air filter

Locate and take out the air filter. You can check your car manual to know the position of the air filter in your vehicle.

Step 2: Clean both sides of the filter with the cleaner

You will notice that the air intake side is dirty because that is where the dirt gets trapped. Spray both sides of the filter with the cleaner. Make sure it’s spread evenly across the surface to dissolve any oil, dirt, or other debris caught in the filter.

Step 3: Rinse the filter by low-pressure water source

Let the filter sit for 10 minutes. Make certain the filter is thoroughly soaked and wait for some minutes. Ensure that the cleaner does not dry on the filter. 

The next step is to get a low-pressure water source to rinse the filter. Clean the filter by rinsing it from the clean side out. If you do the opposite, you will force the dirt and sludge into the filter’s fibers.

Step 4: Gently shake the filter to send out excess water

Gently shake the filter to send out excess water. This will help the filter dry quicker. 

Step 5: Let the air filter air dry naturally

Let the filter sit for 45 minutes to an hour and only dry the filter naturally. Only after you’ve cleaned both sides with the cleanser, rinsed it, and let it air dry can you move on to the next step. 

Step 6: Apply the oil spray carefully along with the filter’s pleats

Apply the oil spray carefully along with the filter’s pleats. If you’re using the air filter oil squeeze, apply it evenly along with the crown of each pleat. Make sure you have a decent amount on the pleats and don’t leave any dry places. Apply the air filter oil lightly to avoid overdoing it. It should only be applied on the side of the air intake.

CAUTION: Do not oil both sides of a K&N air filter.

Only apply oil on the dirty side – the air intake side of the filter that will be exposed to the environment. This will trap the smaller particles while enabling more air to travel through the K&N filter. More than that, if you over oil it, it can pull some oil off the filter and get on your mass airflow sensor when the car is running. This will cause some malfunction. 

Step 7: Allow the oil to be absorbed for 20 minutes and reinstall the filter

Allow the oil to be absorbed into the filter material for 20 minutes before rechecking for any areas that may require additional oil. Wipe away any excess oil that you see on the filter. Be sure it has dried properly before reinstalling the air filter to prevent the oil leak into the engine.
