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.

    Great Product 5 months ago
    4out of 5stars

    (2014 WRX Hatch) At 29k miles my stock engine's oil pickup cracked causing oil starvation -> shattered connector rod -> dead engine. After acquiring a brand new engine from Subaru (ty warranty) I've done everything I can to ensure my engine is bulletproof. The Killer B pan, pickup and baffle in combination with the Cobb AOS has restored my faith in my EJ and I'm finally confident again to push my WRX to it's limits. Installation is a bitch and the instruction on Cobb's website are trash. The techs at Cobb were also confused by their own instructions when I called for help. **I recommend references IAG's AOS installation guide since they're relatively the same.**

    Great looking product with a fairly easy installation process. 6 months ago
    5out of 5stars

    This AOS is a Cobb rebranding of IAG's Street AOS. The finish is sleeker than IAG in my opinion. There is a step-by-step walkthrough with photos on the Cobb website. That tutorial uses the IAG model as an example. This product does not clear the factory strut tower bar. This AOS is great because unlike a simple catch can, you don't need to empty out any oil. It recirculates the oil back into the system. It routes coolant from the expansion tank to heat up the oil before sending it back to the motor. There is a bleeder port to purge the air from the cooling system. It uses two 7/8" open end wrenches. These are not sizes I had in my toolbox, and I ended up slightly marring and ruining the finish of the bleeder port nuts trying to use whatever I had in my toolbox. Be aware of these sizes and have them in hand or find two adjustable wrenches large enough. Overall, this product is a great buy.
