FunnelWeb FWF PRO 7990 Proline Air Filter 2001-2013 Yamaha YZ250F/YZ450F

In the high-revving world of Yamaha 4-strokes, clean air is the difference between a podium finish and a costly engine rebuild. The FunnelWeb Proline Air Filter is a must-have Racing Performance upgrade, featuring a revolutionary pyramid-profiled foam that effectively doubles the surface area of your intake. At Moto-House MX, we understand that maintaining peak horsepower requires consistent airflow, and this filter is engineered to keep your YZ-F breathing clean even in the most brutal track conditions.

Utilizing the latest technology in open-cell polyurethane foam profiling, this filter traps significantly more dust and silt on its outer surface, preventing harmful debris from reaching your valves. The unique 3D pyramid design vastly improves dirt-holding capacity, allowing for longer motos without the performance drop-off associated with traditional flat-surface filters. Rugged, reliable, and easy to maintain, it is the ultimate defense for your Yamaha’s intake system.

Frequently Asked Questions

How often should I clean the FunnelWeb pyramid filter?
While the pyramid design holds more dirt than standard filters, we recommend cleaning and re-oiling after every dusty ride to ensure maximum engine protection and performance.

Is this filter difficult to oil because of the pyramids?
Not at all. You can use your preferred foam filter oil and massage it into the foam just like a traditional filter; the pyramids are durable and designed to stay intact during the oiling process.

Does this replace the OEM filter cage?
This is designed to fit over your stock Yamaha filter cage, providing a seamless and secure fit within the airbox for a quick installation.
