Now all customers can have the same factory service that top professional race teams and OEM customers have received for the last 10 years. Using their new state of the art filter oiling machine, each Twin Air filter is completely submerged in Bio-Oil and massaged to perfection to ensure that all pores are evenly coated. The filter is then placed in a temperature-controlled room to allow the oil to fully cure on the filter. The complete process provides maximum protection and maximum airflow. You just open the resealable bag and install, no mess, no fuss.
