If it is a cotton filter, you will be able to wash and re oil the filter.
Paper elements are disposable, but i wouldnt have thought that they sell aftermarket paper filters!
They are usually cotton, foam, or mesh etc
Cotton filters should be cleaned with the correct detergent, and coated with the protective oil spray, the oil itself adds a fine layer to the filter which helps with the filtering!
As weird as it sounds, when i have used a k&n cotton cleaning kit in the past, it actually recommends to do bout 80,000 before cleaning as the dirt on the filter acts as a filter! lol
Surely they would tell you to use it earlier, so as to make money!
