IAG Universal Air-Oil Separator (AOS)

This is IAG’s maintenance-free air oil separator for this chassis. It is a real PCV control piece, not just a can you have to keep emptying.

• Cast aluminum canister with internal baffling to pull oil out of the PCV stream
• Returns separated oil back to the crankcase so it stays street friendly
• Built for custom applications where the chassis-specific kit is not the right answer
• Helps keep oil out of the intake tract, intercooler, and charge piping

Why you’d want it: if the car sees spirited street driving, track time, or just long-term ownership where you want cleaner intake plumbing and better crankcase control, this is one of the better upgrades you can make.

This one makes sense when you’re building something custom and still want a real baffled separator instead of a generic catch can.

AOS Color: Choose Black, Red from the product options.
