Brand: K&N Engineering
K&N air filters provide excellent filtration with maximum airflow. The oiled gauze filtering media traps and holds more dirt than any paper filter. They can also be cleaned and re-oiled many times, saving money over the long run.
This universal-fit round tapered filter measures 6.5" long x 4.75" OD at the base and 3.5" OD at the top. The clamp-on mounting flange is designed to fit over a 3 5/16" tube. Black rubber end cap.
This filter is commonly used on the Spec Miata intake kit.
