For many years, Twin Air Factory Pre-Oiled filters were only available to our top professional race teams and OEM customers. The results were so good that we now offer the same factory treatment to everyone.

We 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.
