K&N 1988-2009 YFS200 Blaster/Grizzly Air Filter

K&N YA-2088 Performance Air Filter | Fits 1988-2009 Yamaha Blaster & Grizzly

Boost your ATV's horsepower and acceleration with the K&N YA-2088 High-Flow Air Filter. Washable, reusable, and built for dusty off-road trails

Unleash the true potential of your classic Yamaha ATV with the K&N YA-2088 High-Flow Replacement Air Filter. Specifically engineered for legendary trail machines like the 1988-2006 Yamaha YFS200 Blaster and the 2004-2009 Yamaha YFM125 Grizzly, this premium drop-in upgrade replaces your restrictive factory paper or foam element with race-proven technology.

Unlike standard disposable filters that rely on thin paper to mechanically block dirt—subsequently choking off critical airflow—K&N utilizes multiple layers of woven, pleated cotton gauze treated with a specialized tacking oil. This depth-loading engineering creates an intricate, multi-dimensional grid that traps harmful dust, sand, and debris while maintaining a high-velocity stream of clean air straight to your carburetor.

Designed to drop directly into your vehicle's original factory air box, the YA-2088 features an application-specific sealing bead that guarantees an airtight, flawless seal without any cutting, drilling, or custom modifications. Best of all, it provides a clean, predictable air fuel mixture even during drastic altitude changes, meaning no complex jetting modifications are typically required for installation. When the filter finally gets dirty from the trails, you don’t throw it away; simply wash it, re-oil it, and drop it right back in for a lifetime of performance.

Best Uses

1. Aggressive Off-Road Trails: Perfect for recreational riding through tight woods, heavy dirt trails, and mud tracks.
2. Dusty & Sandy Environments: Ideal for ATVs tackling desert dunes, dried-out lake beds, or loose gravel paths where fine dust easily clogs standard filters.
3. High-Altitude Riding: Excellent for mountain trails where maintaining consistent, clean airflow is vital to prevent sluggish carburetion.
4. Vintage ATV Restorations: A must-have mechanical upgrade for restoring and maintaining optimal throttle response on older 2-stroke Blasters and utility Grizzly models.

Features

1. Multi-Layer Cotton Gauze Media: Constructed with multiple layers of premium, pre-oiled woven cotton fibers sandwiched between wire mesh for maximum depth-loading capability.
2. High-Flow Pleated Design: Features a heavily pleated structure that dramatically increases the active surface area, allowing low restriction and immense airflow.
3. Factory Air Box Compatibility: Engineered as a direct drop-in replacement with an integrated flexible sealing bead to ensure a flawless, airtight fit in the OEM air box.
4. Washable and Reusable: Built to outlast your ATV; can be repeatedly cleaned and refreshed using a K&N Filter Care Service Kit.
5. No Jetting Modifications Required: Specifically mapped to work harmoniously with factory carburetor settings under normal operating conditions.

Benefits

1. Increased Horsepower & Throttle Response: By maximizing the volume and velocity of incoming oxygen, your engine breathes easier, unlocking quicker acceleration and more power.
2. Exceptional Filtration Protection: Tested rigorously under ISO 5011 protocols to achieve a 97%–99% overall filtration efficiency rating, defending your engine's cylinder walls and pistons from micro-abrasives.
3. Cost-Effective and Sustainable: Eliminates the ongoing cost of buying disposable paper or foam filters, paying for itself after just a few riding seasons.
4. Extended Service Intervals: The specialized oiled cotton traps dust throughout its depth rather than just on the surface, allowing the filter to perform flawlessly for longer stretches between cleanings.
5. Reliable Performance at High Altitude: Helps counteract the "rich" bogging effects of high-elevation riding by supplying the engine with the cleanest, less-restricted path for air intake possible.
