How to clean a cold air intake filter

A cleaned air intake filter is essential for increased performance and better fuel economy. Most air intake filters get dirty after a while, and sometimes, the filter gets choked with stone chips. 

The PRL, K&N, Injen, and 27WON filters are large 4-inch air intake filters that are washable and can be used for more than 100,000 miles. This dirty air intake filter issue requires proper cleaning; washing it off would not help. Let’s look at some efficient cleaning tips to clean your air intake filter. 

Here is an example of a dirty air intake filter:

  1. Remove the filter from the intake hose
  2. Clean it with compressed air to remove the stone chips and excessive dirt
  3. You can use a soft brush to remove the debris
  4. Spray the air filter cleaner on the filter properly. You can use the most popular K&N air filter cleaner.
  1. Leave the filter for 2-3 minutes to allow the filter to soak in the cleaner chemicals.
  2. Wash it with normal water 
  3. Make sure the water runs through the filter
  4. Dry it using a cloth 
  5. Now you will see the filter cleaned, but it will not be red, like the way it came.
  6. After cleansing, spray the air filter oil or a degreaser over the filter to make it return to its original color. 
  7. It’s done; your filter is new. Install it back in the car to enjoy a better ride.
