As airborn dirt particles are trapped by a paper or cotton-gauze air filter, there is a dramatic increase in pressure drop which essentially robs the engine of airflow and power. Due to the deep foam construction of each Pipercross air filter, airflow is able to negotiate trapped dirt.

Air filter service intervals are extended with the Pipercross panel filter, with a lifespan (between cleaning) of double that of the same paper filter and nearly three times that of a cotton-gauze filter. By simply cleaning and refitting the Pipercross panel filter, there is less waste and service costs are reduced.
