K&N Yamaha YFM Bruin / Kodiak / Grizzly /Wolverine Replacement Air Filter

K&N Replacement Air Filter for Yamaha Bruin/Kodiak/Grizzly/Wolverine | YA-3504

Boost your ATV's performance with the K&N YA-3504 replacement air filter. Washable, reusable, and engineered for high airflow and superior off-road filtration.

Upgrade your Yamaha ATV's performance and protection with the K&N High-Flow Replacement Air Filter (Part No. YA-3504). Specifically engineered to thrive in punishing off-road environments, this premium drop-in filter features multiple layers of pleated, woven cotton gauze media treated with a specialized tacky tack oil. Unlike restrictive paper filters that trap dirt on the surface and quickly clog, K&N's depth-loading design captures fine dust and trail contaminants throughout the layers while maintaining a massive, steady stream of oxygen to your engine.

Designed for a precise fit into your factory airbox, it features an application-specific sealing bead to prevent unfiltered air from bypassing the system. Whether you are navigating high-altitude mountain passes, work sites, or dusty trails, this filter eliminates the need for expensive disposable replacements and is fully washable and reusable for the lifetime of your vehicle.

2. High-Altitude Off-Roading: Ideal for varying elevations, ensuring clean, predictable carburetion and optimal air-to-fuel ratios without starving the engine.
3. Utility & Property Management: Excellent for hardworking Yamaha utility models handling property maintenance, farm chores, and heavy towing where low-speed cooling and continuous performance are critical.
