NOTE: This is for the SEALING RING version of the PowerFlow Kit. If you do not have this version of the PowerFlow kit purchase the standard version of this filter.
This is a PowerFlow Replacement Filter with the inner backfire resistant foam. Now just buy and install. No need to mess with oil.
Twin Air Factory filters have been available only to our top professional race teams and OEM customers. The results have been so good that we now offer the same factory treatment to everybody.
Pre-Oiled Filter Option: 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 reasalable bag and install.
