ProLine Air Filter & Pre-Filter Kit - KTM 790 Adventure, KTM 890 Adventure and Husqvarna Norden 901 Models

The FunnelWeb Filter Pro Series is designed to solve the primary weakness of adventure bike airboxes: rapid clogging in silty or dusty conditions. The FWF-PRO-7339 features a precision-cut "profiled" foam that effectively doubles the external surface area of the filter without increasing its overall footprint. This allows the filter to trap more dust on the outer peaks while maintaining consistent airflow through the valleys, preventing the "suffocating" effect that leads to power loss and poor fuel economy during long off-road stages.

Performance Features

• Pyramid Profile Design: Doubled surface area allows for longer service intervals and more consistent airflow in extreme dust.

• Single-Layer Dual-Density Foam: High-quality polyurethane foam provides superior filtration of even the finest silt particles while maintaining high flow rates.

• Injection-Molded Seal/Cage: The filter features a precision-molded urethane seal that provides an airtight fit against the OEM airbox, keeping "dust dusting" out of the intake.

• Outback-Proven Durability: Specifically developed for the harshest Australian off-road conditions to protect high-performance powersports engines.

• Washable and Reusable: Designed to be cleaned and re-oiled hundreds of times, when done properly, making it a more sustainable and cost-effective solution than paper filters.

• Easy Installation: A direct bolt-on replacement for the factory paper filter, requiring no modifications to the airbox.

• Main Filter Element:  A replacement main filter element is available in case you damege the original or just want to have a second filter that is oiled and ready to go.

Like all FunnelWeb filters, the ProLine Filter features profile cut, single layer, single density foam that doubles the external surface area of the filter without increasing the original filter size. The ProLine Filter traps dirt, dust, sand and mud over a larger area on its outer surface, ensuring optimal air flow is maintained for maximized engine performance and reliability.

The single layer, single density polyurethane foam has the added advantage of being easy to clean and the ability to maintain its original shape after numerous washes. Compared with conventional foam filters, FunnelWeb offers more protection from dirt ingestion, has longer service intervals and maintains high airflow rates when dirty.

Works with any foam air filter oil. We
recommend Motorex BIO Air Filter Oil and the
Motorex BIO Air Filter Cleaner
