Product Description
IAG Off-Road Air Oil Separator | 2.3L (Bronco 2021+)
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 AOS is designed for maintenance-free operation. Unlike conventional catch-can systems, our Air Oil Separators do not require regular draining or upkeep. Oil that has been separated accumulates on the inner walls of the AOS canister and gradually flows down by gravity, returning to the engine's crankcase. Our special heating system prevents the collected oil from sludge buildup, ensuring it can be safely reintroduced back into the engine. The large volume canister of this Air Oil Separator allows for oil to drain back gradually, eliminating the risk of overflow that smaller catch cans may pose.
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.
The IAG Air Oil Separator maintains the functionality of the OEM PCV system, while supplementing its capacity. The IAG Air Oil Separator PCV discharge gasses return to the turbo inlet, retaining a PCV valve to draw additional suction, which helps to improve air oil separation. In ethanol-fueled applications, our AOS safeguards against oil dilution and lubrication issues by capturing fuel vapors from the oil and redirecting them into the intake tract for combustion. The IAG AOS provides superior protection against both oil entrainment in the intake flow and oil dilution in the engine's lubrication system compared to the OEM PCV system on its own.
The IAG Air Oil Separator uses a unique heating system to address a common problem seen in lower-quality catch cans. As hot PCV gasses flow through a cold hose, it creates condensation inside. Over time, this condensation mixes with the oil, causing sludge formation within the system. IAG has solved this issue by attaching the AOS to the vehicle’s cooling system. This allows heat to be transferred from the engine to the AOS. By heating the AOS body to the same temperature as the engine, the condensation and the associated buildup is greatly reduced or nearly eliminated.
Included with our Air Oil Separator is the IAG I-Line Hood Pad Isolator. This low-profile hood pad not only provides more space to accommodate the AOS, but it also contributes to improved engine cooling and reduced hood vibration. Constructed from a flocked fiber material, this sleek isolator features a stylish hexagon pattern that provides extra reinforcement to the pad, while helping to dampen engine noises and vibrations. The IAG Hood Pad Isolator is easy to install, and the entire task can be completed within a matter of minutes. There is no need for cutting, drilling or permanent modifications, the pad mounts up to the existing mounting points under the hood using the included plastic clips.
For the 2021+ Ford Bronco 2.3L EcoBoost, our engineers have created an Air Oil Separator system that is as easy to install. We have developed and included custom injection molded fittings to connect to your Ford’s factory breather ports. These fittings are designed to be plug-and-play with the OEM breather ports, so there's no need for any modifications to the fittings.
Early 2021 models built between 05/03/21 to 11/17/21 have a slightly different PCV system that requires additional hoses (sold separately). Your build date can be found by checking the VIN plate in the drivers door well. Professional installation is recommended on early models due to the complexity of the installation.
The IAG Air Oil Separator is cast from aluminum and features an attractive and durable powder coated finish. The AOS is available in your choice of 3 colors. Choose from Black, Blue or Red to add a touch of style to your Ford’s engine bay.
