FUNNELWEB FILTER AIR FILTER HONDA CRF250R/CRF250RX/CRF450R/CRF450RX 25-26
The FunnelWeb Filter was designed and is manufactured by Infiltration Pty Ltd, an Australian Company with more than 40 years of experience in off road motorcycle foam air filtration within the organisation.Ā Utilising the latest technologies in open cell foam 3D profiling, theĀ pyramid profile effectively doubles the filters outside surface area without increasing its overall size and, compared with conventional foam air filters, have been designed to;
- Trap and hold more dust on the outside surface of the filter
- Maintain optimal air flow by spreading dust build over an increased surface area.
- Enable longer filter service intervals.
The Foam Profile:
- Provides a 100% larger surface to trap more dust
- Traps dust evenly over the increased outside surface area while allowing optimum airflow for longer periods of riding
- Effectively reduces the frequency of filter changes and cleanings.
Impenetrable, robust foam enables a tight fit and guarantees no dirt or debris enters the airbox.The robustness of the seal also reduces the chance of shrinking, stretching, and tearing to allow for optimal fit over its lifetime.
