K & N Air Filter - EX250R Ninja KA-2508

A restrictive factory air filter limits your engine's breathing potential and forces you to service it more frequently than necessary. The K&N KA-2508 delivers measurably higher airflow to your EX250R Ninja's intake while maintaining superior filtration—meaning better throttle response and longer intervals between cleanings. This is a straightforward bolt-on upgrade that requires zero fuel management adjustments and fits directly into your OEM airbox.

K&N's pleated media design expands the filtration surface area, allowing more air to reach your engine while trapping contaminants effectively. You'll notice the difference in how your bike responds, especially in the mid-range where a Ninja 250R rider feels every performance gain. Built in the U.S.A. with application-specific engineering, this filter is engineered to stay sealed and perform for thousands of miles.
