A first layer of ventilated foam traps dust, sand, and impurities. A second layer of denser foam stops finer particles while promoting airflow.

And the third fireproof layer allows for replacing the firewall of the original filter.

The adhesive that bonds these layers has been specially developed for Twin Air filters and ensures the layers' fixation. Twin Air filters are smaller than stock ones so you can increase the volume of the filter box and enhance airflow. The exclusive design of the “breathable seal” 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 perforate the cylinder, piston, and rings.
