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!

Nice, looks like an improved version of the Prova.
Except it's not overpriced.

yea, and ours actually vents the crankcase as well.

what are the benefits compared to the crawford AOS?

Thanks!

what are the benefits compared to the crawford AOS?

Thanks!

The 2 main benefits are  1) that you are able to run the oem PCV which we found in testing is really important 2) their oil return has had "gravity" issues, ours will not.

Also ours is much more compact of a design.

Short product vid...

Just installed mine. Really happy with the quality of the piece.

Some advice for others: Do not try holding onto the threads with your palm and unscrewing it. A) You're doing it wrong and B) those threads will slice into your palm like a son-of-a-itchbay.

My research couldn't find any issues with cold weather... have you guys had any reports of them freezing up like others have been known to do?

[GrimmSpeed]

It won't freeze up but you may notice some condensation and milkyness during the colder seasons. This is nothing to worry about though, it's normal inside of every engine!

Mike

are you sure about this?

i took out my AOS due to that fact that it was condensing in the cold and i had a itshay load of water in my engine...that "milkyness" and last time i checked any amount or kind of water in your engine is bad news bears! i had my previous engine blow up in result of this....the water or "milkyness" rusted a bearing and poof...so when i saw this happening again i quickly removed the AOS and it took 3 engine flushes to get it all out....

IN MY OPINION no AOS is worth it.......

I'm sure you have a very good prodcut and have done all your research but i wont take the chance again with any AOS.

Indeed.. you may want to address this.  Crawford implemented a coil heater for that very reason. Are you suggesting it's unnecessary?  Just a heads up to potential buyers.

[mudferret]

I've pondered a GS AOS, but I am curious about the cold issue as well.  I think the design tends to scavenge heat from the engine itself, there's a surprising amount of heat available at the filler neck.  I have no empirical evidence to back this assumption up however.

Actually this is precisely why we placed it where we did. The oil fill location is heated by the engine and with the metal placed there it will get warm quickly and remain warm. The big issue with condensation is that it likes to collect on cool metal surfaces. this is also why we made our AOS so small. Yeah the different competition's AOS' are large and pretty and that's great, but as far as surface area goes that have an extremely large (comparatively) surface, larger cool metal surface = way more condensation, thus the need for them to create a warming function. Ours is small enough and in an already warm location.
