Funnelweb's profile cut foam effectively doubles the filters external surface area, without increasing the filters original size, enabling it to trap and hold far more dust on the outer surface. This means more protection for the engine while maintaining optimal air flow and extending filter service intervals.
The single layer, single density polyurethane foam has the added advantage of ease of cleaning and the ability to maintain its original shape after numerous washes. As dirt is spread over a much larger surface area, airflow restriction caused by dirt build up is minimized substantially. Overall, compared with conventional foam filters, the Funnelweb offers more protection from dirt ingestion, has longer service intervals and maintains high airflow rates when dirty.
Most Funnelweb Filter seals are constructed from injection molded urethane for a lasting, precise fit on the filter support frame and the inside of the air box. Foam seals will tend to stretch out of shape after a few washes, resulting in a poor fit to the support frame and possibly affecting the filters sealing ability.
