This is the IAG Performance V3 Street Series Air / Oil Separator. This latest design prevents harmful oil or vapors from coating your intake system which can lead to a lack of performance and long-term engine damage.
KEEPS OIL OUT
Keeping oil out of the engine intake tract is extremely important in preventing premature mechanical failure and maintaining performance
Prevents oil from coating the internal portions of the intake, intercooler, and piping
Prevents premature failure of the rubber or silicone hoses, which can lead to failed connections
Once the oil reaches the intake tract it will directly enter the intake manifold and then the combustion chamber of the engine
Oil inside of the combustion chamber can cause detonation and preignition, high emissions, smoke, loss of power, decreased gas mileage, and even catastrophic engine failure leading to expensive repair bills
PCV RECIRCULATION
The Street Series maintains the OEM PCV system functionality but supplements its capacity
The AOS PCV discharge gasses return to the turbo inlet, retaining a PCV valve to draw additional suction, improving air oil separation
Protects from oil dilution and lubrication failures in ethanol-fueled application because the Street Series AOS captures fuel vapors out of the oil and returns these vapors to the intake tract for combustion
Protects from both oil entrainment in the intake flow and oil dilution in the engine's lubrication system far better than the OEM PCV system alone
