FunnelWeb ProLine Air Filter for Yamaha YZ & YZ-F Models

The FunnelWeb ProLine air filter is designed for demanding conditions and maximum engine protection in dusty and sandy off-road terrain. Its unique single-layer, pyramid-profile foam dramatically increases surface area compared to a standard flat foam filter. That added surface area allows the filter to trap more dirt while maintaining strong airflow and consistent performance over longer rides. Built with high-quality foam and a robust urethane sealing base, the ProLine filter is made to withstand repeated cleanings and harsh off-road use.

Features:

• Pyramid-profile foam design increases surface area for improved dust loading and airflow

• Single-layer, fine-density foam delivers excellent filtration without restricting performance

• Durable urethane sealing base ensures a secure, airtight fit

• Washable and reusable for long service life

• Designed for off-road, enduro, and motocross conditions where dust protection matters most
