Kawasaki KX450F Air Filter - ProFilter - Ready-To-Use - `17-`18. This ProFilter ready-to-use air filter is made to replace the stock element on 2017–2018 Kawasaki KX450F (also fits KX250F of the same years) and comes pre-treated so it can be installed right out of the box.

Engineered as a direct-fit replacement, this ProFilter unit uses high-quality foam construction designed for repeated service. The ready-to-use treatment saves prep time before installation, and the filter is intended to be cleaned and re-oiled per the manufacturer's care instructions to extend service life. It’s a practical choice for riders who want a reliable, reusable filter that matches factory fitment and simplifies maintenance.
