Description
An Air/Oil (AOS) Separator has one job, remove the oil from the engine ventilation system so the oil does not get sent through the intake system. The GrimmSpeed AOS has a unique patent pending design that allows you to maintain your PCV Valve while separating the oil out of the crankcase and head ventilation air!

Removing oil out of your intake system will result in a more efficient engine. An Air Oil Separator takes the place of an oil catch can or tank, resulting in you not having to empty your oil catch can. As well as being very subtle and not noticeable.

Another benefit to this unique design is the compact and clean look; making this ideal for someone who wants to keep it looking stock under the hood.

Picked this up after noticing piles of old oil in my intercooler and Y-pipe. Mine didn't come with instructions, but Grimmspeed has a video on how to install it. Had to get creative with the hoses after my old ones split trying to use the supplies tubing joiners. Otherwise, install was straightforward, and it looks cool under the hood. I did have to turn the barbs about 25 degrees clockwise to free up my dipstick.

Love this piece

This is a great product, id recommend it to anyone with a wrx or Sti, stock or built. It's super easy to install, if you have any questions grimmspeed makes a good video with instructions. My dad develops motors for Hyundai and he loves the design, it's affordable, it's effective and easy for anyone to install. It's something each wrx or Sti owner should have.

It works.

This product is very well built and it solves several issues in a stock WRX. My wife's 2011 STI is sporting one solving the old oil in the intercooler issue as well as a lean condition caused by the stock crank case breather setup emulsifying the oil and winter time moisture clogging the whole system. Looks cool, works great, worth every penny believe it or not. Grimmspeed is awesome if you weren't already aware.

Works great on our 2015 STI!

Works just like it should. It keeps our intake and intercooler free from oil and looks great while doing so!

  • Q: Instructions for fmic  xsaint7741060 1 year ago

    Answer

    Are there directions for a fmic


    • A: If you have a FMIC, the instructions are identical except the bottom right port on the AOS will not go to the oem head breather hardline, it will go to your existing “T” for the head breathers.

  • Q: what is the difference between this and Perrin/Crawford based AOS systems?  Evren 1 year ago

    Answer

    if you could shed some light that would be great on my order decision. Thanks


    • A: This system routes blow by back to the oil feed tube, it is also unbaffled and not recommended due to the location for heavy track use. The Crawford and Perrin AOS systems are coolant cooled and work very well for track applications. This is a simple AOS that doesn't break the bank and is much easier to install than the other two.

  • Q: tune  Tyson DesRoches 1 year ago

    Answer

    does this require a tune?


    • A: Tuning will not be needed for any AOS system, as it does not effect the ECU or tuning calibrations.

  • Q: fitment differences  TremendousWRX 2 years ago

    Answer

    Is there any fitment differences between this AOS and the AOS specified for the 2008+WRX aside from hoses and connectors? I am wondering if I can buy this one, and buy some 1/2 inch fuel hoses and connectors, and swap it between the two cars.


    • A: This AOS body is the same as the other model and the only differences are the hoses and connectors. You could use this AOS on a 2008+ WRX if you sourced your own fittings and hoses.

  • Q: supplied hose size  shiroikage 2 years ago

    Answer

    What size is the hose supplied with the AOS? would you have the hoses in red to purchase along with the kit?


    • A: The hose supplied in this kit is 1/2. We currently do not offer the hose in any other colors than black. -Matt H.
