Pre-lubricated air filter Twin Air for Honda CRF 250 / 450

Pre-oiled air filter Twin Air for Honda CRF 250 / 450 R / RX.

Thanks to its patented design and high-quality materials, Twin Air filters guarantee unmatched performance and protection levels to date. That is why OE manufacturers and the best riders in the world choose Twin Air.
A first layer of ventilated foam traps dust, sand, and impurities. A second, denser foam layer stops finer particles while promoting airflow. The adhesive that bonds these layers has been specially developed for Twin Air filters and ensures the layers stay fixed. Twin Air filters are smaller than factory ones so you can increase the volume of the filter box and enhance airflow. The exclusive "breathable gasket" design guarantees maximum contact surface with the filter box body. Trapped particles can restrict airflow. If dirt gets into the engine, just one particle the size of a pinhead can damage the cylinder, piston, and rings.
