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. No more having to check/empty your catch can and refilling your oil. The GrimmSpeed™ AOS coalesces oil without using a mesh media. Mesh media can cause contaminates to collect and build up resulting in possible sludge. 

AOS will allow your engine to run more efficiently due to the separation of oil from the intake system.

When there is oil in your system, the result is:

  • 1) reduced fuel octane
  • 2) higher chance of engine knock(detonation)
  • 3) worse emissions
  • 4) higher oil consumption. 

The GS Air/Oil Separator will help all of these problems

In typical GrimmSpeed™ fashion, they have made a very compact unit that packs a powerful punch (and looks good while doing it)! 

Our AOS is self-maintained so you can just sit back, stop worrying, and enjoy driving your car!

Please note this product is designed to combat factory amounts of blow by. If you have a built motor or are experiencing abnormal amounts of oil consumption, this product may not work for you.
