• For many years, Twin Air Factory Pre-Oiled filters were only available to top professional race teams. The results were so good that Twin Air now offer the same factory treatment to everyone. They start with an Original Dual-Stage Air Filter and completely submerge it in BIO Liquid Power Filter Oil. After the filter is massaged to ensure all pores are evenly coated with oil, it’s placed in a temperature-controlled room to allow the oil to completely cure. You just open the resealable bag and install.
