FUNNELWEB FILTERS DESERT AIR FILTER YAMAHA YZ250F/YZ450F

Description

FunnelWeb FWF520DE Desert Air Filter – Yamaha YZ250F / YZ450F

Take on dusty motocross and off-road conditions with the FunnelWeb FWF520DE Desert Air Filter. Designed for high-dust environments, this Australian-made performance air filter combines FunnelWeb’s unique pyramid-profile foam technology with increased dirt-holding capacity, strong airflow and longer service intervals.

Australian Made Performance

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

The pyramid profile 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 FWF520DE to trap and hold significantly more dust before airflow becomes restricted.

By spreading dust evenly across the larger outer surface, the filter helps maintain optimal airflow for longer periods of riding while reducing the frequency of filter changes and cleaning.

FunnelWeb’s high-capacity foam design is also designed to provide around twice the service life between cleans compared with a conventional foam air filter under similar riding conditions.

Built for Dusty Riding Conditions

The Desert-spec FunnelWeb filter is particularly well suited to riders tackling dry, dusty motocross tracks, trails and off-road environments where conventional filters can quickly become loaded with dirt.

Its increased filtration area helps capture more airborne contaminants while continuing to provide the engine with the airflow required for consistent performance.

Durable Foam Seal

The FWF520DE features a robust die-cut foam sealing system designed to create a secure fit against the airbox.

The durable foam helps prevent dirt and debris from bypassing the filter while also reducing the chance of shrinking, stretching and tearing over the filter’s service life.

Why Choose a FunnelWeb Desert Air Filter?

When riding in heavy dust, greater dirt-holding capacity can mean more time riding and less time servicing filters. FunnelWeb’s Australian-made pyramid-profile design provides twice the external filtration surface area of conventional flat foam, helping the FWF520DE capture more contaminants while maintaining airflow for longer.

For Yamaha motocross and enduro riders looking for reliable engine protection in demanding dusty conditions, the FunnelWeb FWF520DE Desert Air Filter is a durable, high-performance filtration upgrade.
