Ride longer between filter changes with the FunnelWeb Proline Filter — designed and manufactured in Australia by Infiltration Pty Ltd, drawing on over 40 years of experience in off-road motorcycle foam air filtration.
The secret is the unique pyramid profile, which effectively doubles the filter's outside surface area without increasing its overall size. Compared to conventional foam filters, this traps and holds more dust on the outer surface, maintains optimal airflow by spreading dust build-up over a larger area, and enables significantly longer service intervals. Proven in the harshest off-road racing conditions worldwide, it's serious engine protection you can rely on.
Most FunnelWeb filters feature a urethane/foam combination seal built for strength and longevity — it won't shrink, stretch or tear, and maintains a positive air-tight seal to your airbox so every bit of air entering the engine passes through the oiled foam.
