Features & Product Details

RallySport Direct is always proud to carry quality automotive performance products brought to you by COBB Tuning. 

On this page, you are looking at the COBB Tuning Air/Oil Separator that has been designed to prevent oil and vapors from entering your intake manifold. This design installs in your crankcase ventilation system and prevents buildup on your valves which can certainly have an effect on your performance. 

Here are the details:

  • Billet aluminum tank design
  • Bespoke COBB anodizing on caps
  • Wrinkle black powder-coated canister
  • Laser etched COBB logo
  • Developed in partnership with IAG Performance
  • 4" OD and a 5.75" height
  • Heat shielding on crankcase breather and oil return lines
  • Coolant bleeder valve
  • Port connections from the AOS to the cylinder head and to the top of the block
  • Bottom of the canister is shaped like a snail which redirects positive crank pressure into the same swirl pattern produced by the 3 side ports which allows for maximum oil drainage while separating oil from the air in all of the venting ports
  • The back plate of the AOS features a unique coolant routing system that heats the entire AOS to the same temperature of the engine which maximizes the evaporation of any water collecting inside of the can 
  • All hoses, fittings, hardware, and brackets are included making this air/oil separator system ready for the installation.

    QUESTIONS & ANSWERS

    • Q: Draining  Plazma1 month ago

      Will this require draining over time?
      • 1 of 1 people found the following answer helpful

        A:  There is an oil drain at the bottom of the unit, it will be routed back in to the engine meaning you shouldn't need to drain this AOS.

        A:  Yes you will be able to smog with this AOS. An air oil separator should not effect emissions testing.
