Killer B Air Oil Separator w/ Plumbing - 2008-2014 WRX, 08+ STI

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
