FUNNELWEB FILTER BETA 4 STROKE ENDURO AIR FILTER

Description

FunnelWeb FWF401F Air Filter – Beta 4 Stroke Enduro 2020-2026

Upgrade your Beta 4 Stroke Enduro with the FunnelWeb FWF401F Air Filter, an Australian-made performance foam filter designed to deliver exceptional engine protection, increased dust-holding capacity and longer service intervals in demanding off-road conditions.

Suitable for Beta 4 Stroke Enduro models from 2020 to 2026, the FWF401F uses FunnelWeb’s distinctive pyramid-profile foam technology to help keep your engine breathing cleanly even when the riding gets dusty.

Australian Made Performance

Proudly designed and manufactured in Australia, FunnelWeb Filters use advanced open-cell foam and precision 3D profiling to create their unique pyramid-shaped filter surface.

This innovative design effectively doubles the filter’s external surface area without increasing its overall size, providing approximately 100% more surface area than conventional flat foam.

Twice the Surface Area, Longer Between Services

The increased external surface area allows the FunnelWeb FWF401F to trap and hold substantially more dust and dirt before airflow becomes restricted.

Dust is distributed evenly across the pyramid-profile foam rather than concentrating in one area, helping maintain optimal airflow for longer periods of riding.

The increased dirt-holding capacity also helps extend filter service intervals, with FunnelWeb filters designed to last around twice as long between cleans compared with a conventional foam air filter under similar riding conditions.

Built for Dusty Off-Road Conditions

Whether you’re riding enduro trails, racing or tackling dry and dusty terrain, keeping contaminants away from the engine is essential.

FunnelWeb’s pyramid-profile foam provides a larger filtration area to capture dust and debris while continuing to supply the engine with the airflow it needs for reliable performance.

Durable 13mm Foam Seal

The FWF401F features a durable 13mm die-cut foam seal designed to provide a firm and secure fit beneath the filter support frame.

The substantial sealing surface helps prevent dust and debris from bypassing the filter and entering the airbox, while high-quality gasket foam reduces the likelihood of shrinking, stretching or tearing over time.

Chemical & Heat Resistant Construction

Specially blended adhesives are used throughout the filter construction to provide long-lasting durability.

These adhesives are designed to remain unaffected by fuels, oils, cleaning chemicals and heat, making the FWF401F well suited to repeated cleaning, oiling and demanding off-road use.
