Eventuri replacement filter, the filter is a custom design which was developed to provide optimum airflow through the Eventuri housings where the filter is reverse mounted. It is a direct replacement for all of the Eventuri intakes which use Eventuri carbon housings. Filters are recommended to be cleaned every 5000Km with either compressed air or with a cleaning kit. Of course if you do not want to take any risks you can replace them. * Price includes one filter.
