The K&N X‑Stream top replaces the upper section of a round air filter with a 14" OD chrome top that helps feed more air to the engine while retaining the washable, reusable nature of K&N filters. X‑Stream tops mount to existing filters to alter airflow dynamics and are serviceable like other K&N elements, offering a one‑year limited warranty and the long‑term benefit of washable reuse rather than throwaway replacement.
