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.\n\nFANTIC125 XX 24-250 XX 24-300 XE 24-\n\nGAS GAS MXMC125 21-23MC250 22-23MC250F 21-23MC350F 22-23MC450F 21-23\n\nGAS GAS ENDUROEC250 21-23EC300 21-23EC250F 21-23EC350F 21-23\n\nGAS GAS XCEX250 22-23EX300 21-23EX250F 21-23EX350F 21-23EX450F 21-23\n\nKTM MX125 SX 16-22150 SX 16-22250 SX 17-22250 SX-F 16-22350 SX-F 16-22450 SX-F 16-22\n\nKTM ENDURO125 XC-W 17-19150 XC-W 17-19250 EXC 17-18300 EXC 17-18250 EXC-F 17-23350 EXC-F 17-234502
