Upgrade your dual-sport machine with the K&N Replacement Air Filter (Part YA-2509), specifically engineered to enhance the performance and longevity of your 2009-2013 Yamaha XT250. Known worldwide for race-proven technology, K&N drops a premium performance upgrade directly into your bike's factory air box without requiring any complex modifications or carburetor adjustments.

Unlike traditional disposable paper filters that restrict airflow as they capture dirt, K&N utilizes a state-of-the-art design featuring four layers of breathable, woven cotton gauze media. Sandwiched between ultra-fine coated aluminum mesh, this pleated design significantly increases surface area to "rectify" and smooth out incoming air. It delivers up to 50% more airflow to the engine while maintaining strict, exceptional filtration standards. Pre-oiled and ready to install right out of the box, it features an application-specific sealing bead for an airtight fit that blocks contaminants completely. Best of all, it is entirely washable and reusable—engineered to be the last air filter your Yamaha XT250 will ever need.
