GrimmSpeed Black Air Oil Separator Subaru Legacy GT 05-15

Our 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. Our Air/Oil Separator will help all of these problems.

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

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!
