K&N X-Stream Airflow Top Plates
K&N X-Stream airflow top plates have been designed to replace the top of your existing round filter, thereby, adding additional filter surface area for increased airflow. The addition of this component also redirects airflow inside the filter to pull-in more air for even greater performance efficiency. Cleanable and reusable, the X-Stream airflow top filters deliver the best protection available for your engine and are offered in a wide range of applications. The filter top has a 9 in. outside diameter featuring durable black powdercoated trim with K&N logos embossed around the rim. Order the K&N X-Stream airflow top plate designed to fit your application needs.
