The great thing about K&N filters is that they can last up to 100,000 miles before needing to be serviced. Cleaning your K&N filter has never been easier and requires a few more steps in order to work properly again. Other air filters must be thrown out, but the K&N air filter is 100% washable and reusable.
Air filter cleaning is necessary to remove all dirt and debris that has built up over the years. Once you have removed your K&N filter, the first thing you can do is shake it out to remove loose dirt and debris. The K&N cleaning kit is required for both cleaning and re-oiling purposes. It includes all necessary products you need in order to remove dirt properly and get it back to the best working condition.
K&N filters should not be rinsed under water or hosed down in any way. This will damage the cotton media that they are made from. The cotton media must be oiled so catch dirt and debris from entering the engine. This also makes it last longer than any other performance air filter. Also, cleaning the K&N filters with anything other than the K&N service kit will void the warranty.
The products in the kit works by dissolving the dirt and debris embedded in the cotton media. The degreaser also removes any grease that has adhered to the air filter overtime. Once the K&N performance filter is cleaned, it will work just like new again and last you for another 100,000 miles.
