FUNNELWEB FILTERS YAMAHA YZ85 AIR FILTER

Description

FunnelWeb FWF491 Air Filter – Yamaha YZ85 2002-2025

Give your Yamaha YZ85 reliable engine protection in demanding motocross and off-road conditions with the FunnelWeb FWF491 Air Filter. Proudly Australian made, this high-performance foam air filter uses FunnelWeb’s unique pyramid-profile technology to dramatically increase filtration area, hold more dust and maintain optimal airflow for longer.

Australian Made Performance

Designed and manufactured in Australia, FunnelWeb Filters are backed by more than 40 years of experience in off-road motorcycle foam air filtration.

The FWF491 uses advanced open-cell foam and FunnelWeb’s distinctive 3D pyramid-shaped profile, effectively doubling the filter’s external surface area without increasing its overall size.

Twice the Surface Area, Twice the Service Life

Compared with conventional flat foam filters, FunnelWeb’s pyramid-profile design provides approximately 100% more external surface area.

This allows significantly more dust and debris to be trapped across the outside of the filter while spreading contamination evenly over a much larger area.

The result is greater dirt-holding capacity, optimal airflow for longer and service intervals designed to last around twice as long as a conventional foam air filter under comparable riding conditions.

Maintains Optimal Airflow for Longer

As a conventional air filter becomes loaded with dust, airflow can progressively become restricted.

FunnelWeb’s increased filtration area distributes dust across the pyramid-profile surface instead of allowing it to concentrate in a smaller area, helping the engine continue receiving strong airflow even as the filter collects dirt.

This makes the FWF491 particularly well suited to dusty motocross tracks, trails and demanding off-road riding.

Durable Foam Seal

A robust die-cut foam sealing system provides a tight and secure fit against the airbox, helping prevent dirt and debris from bypassing the filter and entering the engine.

The durable sealing foam is also designed to resist shrinking, stretching and tearing, helping maintain an effective fit throughout the filter’s service life.
