GrimmSpeed Air/Oil Separator - Product Release - Subaru Impreza GC8 & RS Forum & Community: RS25.com

**GrimmSpeed** · 01-18-2010, 09:07 AM

You want an AOS that breathes both the Heads and Crankcase? Check.
You want a compact AOS that will work on all models? Check.
You wan a AOS that is not overpriced? Check.

PRICE: $299.99

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.

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! 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 AOS will solve all of these problems.

In 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!
Replaces oil cap for a self-sufficient design that requires ZERO maintenance!

Oil cap replacement?

**jnorth85** · 01-18-2010, 10:44 AM

very nice indeed! I have the Prova now, but it is almost too tall, and under hard acceleration it will rub the hood pad.

You will be placing a "T" after the crankcase outlet, one side of the T will go to the PCV Valve and the other side of the T will go to the AOS.
