The S - FLO IntakeThe AWE S - FLO Intake packs the same power as the full carbon intake, minus the carbon. The AWE S - FLO Intake is comprised of two key components (1) The washable S - FLO Filter and (2) our high - flow, 4 - ply Nomex, fluorosilicone lined, steel wire reinforced silicon air tube. Together, its a free - flowing match made in heaven, allowing optimal flow geometry through the inlet, center section, and outlet of the tube, keeping things tight with our custom molded lip for a perfect seal to the airbox.
