General description:
The K&N performance air filter consists of two layers of wire mesh with a layer of cotton gauze between them, treated with a special oil. This makes the filter more free-flowing, which increases engine power, while the oiled gauze also cleans the air better. Because the filter is made of cotton, it never needs replacing: simply wash it with a special cleaner, let it dry and re-oil it with air filter oil.
