IAG Blue Air Oil Separator AOS For 2021 + 2.3L Ford Bronco - IAG-ENG-F7902BL

IAG now offers the IAG Air Oil Separator for the 2021+ Ford Bronco 2.3L EcoBoost. The IAG AOS is an excellent investment to maintain peak performance in your Ford engine. Our AOS design is based on years of extensive research, development, and testing. It features a spacious 1-liter cast aluminum swirl pot canister that more effectively separates oil from the PCV system upstream of PCV gasses’ return to the intake system. With its heated cast aluminum housing, exceptional venting, and exclusive baffle design, the IAG AOS stands out from the competition. Compatible with all fuel types, our AOS prolongs engine life, enhances crankcase ventilation, and works seamlessly with standard ECU calibrations.

The IAG Air Oil Separator features a distinctive baffle system that enables the oil suspended in your engine's PCV gasses to gather and return to the crankcase. Each inlet hose is positioned on one side of the AOS canister, which helps to create a vortex of the gasses inside. As the gasses move within the vortex, they pass through a series of baffles that collect the oil, while allowing the gasses to escape from the top of the AOS. Because the OEM PCV operation is maintained, the engine draws an additional vacuum on the AOS assembly, further eliminating the PCV gasses.
