Features & Product Details

Air/oil separators are a common upgrade and modification for the Subaru EJ as harmful oil vapors like to make their way into the intake which can create many problems. This will coat the valves with oil and soot, your octane rating will be effective and you will have detonation issues as well. 

The Killer B Motorsport Air/Oil Separator is the result of years worth of engineering, along with research and development to remove oil in liquid and vapor form from the vented crankcase gases. This will prolong the performance and the life of your engine to reassure that your engine is performing at peak levels without worrying about the prevalent air/oil separation issues found in the Subaru crankcase ventilation system. 

 

 

 

SPECS:

  • Accelerated flow of blow-by gases forces suspended oil droplets out of suspension 
  • Centrifugal filtration is a proven process for separation for many particle types and sizes 
  • Collected oil drains back into the crankcase where it belongs
  • Applies vacuum to the crankcase improving ring seal, reducing oil consumption, and improving power potential
  • No media to clean/replaces baffles to inhibit crankcase flow
  • Billet 6061-T6 construction
  • TIG-welded
  • The Killer B Motorsport push-lock barb fittings require no hose clamps
  • Made in the USA

    My Subie shop said it was quite the PITA to install this (About 3.5hrs). Especially since there are zero instructions and just a poorly produced video by Killer B. Hopefully it'll perform well enough to forget about the install.

    QUESTIONS & ANSWERS

    • Q: Install..?..  MikeW1774 years ago

      I’m interested in this AOS, but I am unable to find any installation guides to see if it’s best for me.

        A:  They have a PDF on their site for the install: https://www.killerbmotorsport.net/media/product_instruction/KBM_AOS_Install_Guide.pdf A heads up about it's location/mounting. If you have a strut tower bar ( have a Cusco on my car) you will have to modify the bracket to lower the AOS for clearance, which also may put the drain line, from the bottom of the AOS too low and not allow the oil to drain back into the crankcase. Their AOS catch can add-on will solve that issue. I've added a photo of how the bracket will need to be modified to clear, with my set up on my '11 Sti Hatchback.
