K&N Kawasaki EX650 Ninja 649 17-21 Air Filter

K&N Engineering has been making performance air filters for over 40 years, and they're known for their washable, reusable cotton gauze filters. This direct-fit air filter, part number KA-6517, is built to replace the stock filter in a range of Kawasaki motorcycles, including models like the Ninja 650 and Z650. It's designed to give your engine a bit more breathing room.

The filter uses multiple layers of woven cotton gauze media, pleated to give it a large surface area. This setup allows for low restriction, meaning your engine can pull in more air, which can lead to improved horsepower and torque. Because it's washable and reusable, you can clean it and reinstall it, making it a solid option for long-term use. It comes pre-oiled and ready to install right out of the box, with a base seal and sealing bead designed to fit your specific application.

This filter is made in the USA and comes with a No-Hassle Lifetime Limited Warranty from K&N. It's a straightforward replacement for your stock air filter, aiming to provide better airflow and engine protection.
