K&N KTM 125/200/250/300/380/400/450/520/525/540/560 (Various Years/Models) Replacement Air Filter

The K&N XStream Series air filter is built with an extra filter element inside the top, which significantly increases the total filtration area. This design is key for high-performance motocross bikes where airflow and capacity are critical. It helps ensure your engine gets all the air it needs, even in tough conditions.

This filter uses pleated media to create a large surface area, giving it great dirt-holding capacity and allowing for high airflow. The two-piece construction makes installation and removal easier on modern narrow-frame MX bikes. For added protection, it features epoxy-coated aluminum wire mesh that acts as a backfire screen, shielding the filter element from debris. A custom base seal is included to ensure it fits precisely and securely in place. Plus, it's washable and reusable, coming pre-oiled and ready to install right out of the box.

This filter is designed to fit a wide range of KTM motocross and off-road models, including bikes like the 125 EXC, 250 SX, and 450 SMR. It's a solid option for riders looking for improved airflow and long service life.
