K&N Air Filters and FRAM Air Filters have both been industry leaders in providing air filters for motor vehicles. They both provide great quality for their respective price points.

What should determine the filter for you is how much would you like to invest in it and how important is the performance and reliability of your car to you.

Typically air filters are recommended to be replaced every 12,000 miles especially if you are replacing with a typical FRAM Air Filter. Alternatively, a K&N Air Filter may be cleaned once it’s dirty and has a lifetime warranty.

Changing your own air filter is relatively easy for most cars. If you are uncertain, consult your owner’s manual or your local dealer for further help.

  1. Use proper protective gear for yourself

  4. Using a shop vacuum clean the filter housing to remove dirt and dust
  5. Install your new filter insuring that it is sealed along the perimeter
  6. Replace cover and re-tighten wing nuts and fasteners
