Keep Oil From Subaru's Intake System Without Removing PCV
An Air/Oil Separator has one job: remove the oil from the engine
ventilation system so the oil does not get sent through 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. This AOS will solve all of these problems, allowing the engine to run more efficiently.
The GrimmSpeed AOS is unique as it allows you to maintain your PCV Valve while separating the oil out of the crankcase and head ventilation air
. No more having to check/empty your catch can and refilling your oil.
The GrimmSpeed AOS coalesces oil without using a mesh media. Mesh
medias can cause contaminates to collect and build up resulting in
possible sludge. Our AOS is self maintained so you can just sit back,
stop worrying, and enjoy driving your car!
