air filter fits CRF 250 14-17/ CRF 450 13-16 3-layer non-flammable

Three-layer motorcycle air filters have three different layers of foam filter, a coarse outer layer and two fine inner layers, which work together very effectively. After the outer layer pre-filters the air, the inner layers remove fine dust particles. Air filters are like the lungs of a motorcycle; a dirty or leaky air filter reduces the air supply to the engine. Three-layer filters, also known as non-flammable filters, are designed for extremely dusty environments and can also be used in high temperatures because they are resistant to high temperatures. The air filter must be kept clean and lubricated. The air filter can be used repeatedly and can be washed. Use designated cleaning agents to clean the filters. To lubricate the filter, you can use filter oil, which is available in liquid or spray form. Coat the edge of the air filter with special grease to increase the filter's adhesion to its designated location. In very dusty environments, the air filter can be further protected with an air filter cover. When washing the motorcycle, remove the air filter and replace it with the filter cover.
