A clean side separator catches oil vapor being pulled back into your intake tract, on the opposite side from where a catch can works. On a direct-injected EcoBoost there is no fuel washing the intake valves, so oil vapor bakes onto them over time and costs you power.
why this one — This is the UPR kit built specifically for the 2011-2014 3.5L EcoBoost, not a universal part. It uses push-button Plug N Play fittings so the line comes off without tools.
No power claim by design; catches oil vapor on the clean side of the intake.
