Look up a "cyclonic separator", that's exactly what an AOS is.
No filter media necessary.
The guys who would open up an AOS/catch can and stuff it with pot scrubbers or steel wool to keep oil out of the intake are putting a bandaid on a tired engine.
The Provent works similarly to an oil/fuel filter which is why it needs an element separating the input side from the output side.

Okay, interesting. So, couple follow up's @V2Rocket , where exactly would we plumb the drain on one of those separators, and would it be worth running one in series with a catch can, for those of us who..... may have already invested in new shiny components

Right, maybe some sort of accumulator & a line that merges into the turbo drain on the upper sump? The only thing that worry's me is a combination of air & oil back-flowing into the turbo, so maybe it would have to drain somewhere else..... like a catch can maybe?

In Post #32 from Vlocity "I ran the discharge line from the Provent into a catch can in the driver side fender well just to be safe ...but after two full track days there was not a single drop of oil.....so I have now placed the discharge line into the low pressure area under the car in order (with a v shaped cut on the end) to provide additional vacuum draw through the Provent. The oil in the Provent is routed to the oil pan via a T in the dip stick.
So to summarize I am pulling crank case ventilation from a 1 inch line at the crank cover plus the 2-3/8 lines from the passenger side. I am bringing fresh air into the drivers side via the oil fill. With 10 PSI boost for very long sustained periods of time, I have no oil in the intake, no smoke and no oil in the to atmosphere line"

Recommended Method for Installing Injectors
For our cast aluminum manifold, make sure you install the injectors into the intake manifold first, individually. Also best to use some sort of lube on the injector o-rings such as a dielectric grease. The injector ports are the same size as the ones in the factory manifold, but require some effort to insert the injectors. If you leave the injectors in the rail and try to install it as an assembly you risk them not seating into the manifold properly.

Manifold received today.... I have quite a bit of drool to clean up. Thanks to Mike and Alan for working out the design and implementation of all these custom parts that make this possible without hundreds of extra hours of fabrication work.
Thank you!
Thank you!

Thanks Craig! We are really excited to see all these builds come together. Everyone please be sure to post pictures or send them to me so that I can post via BBG. Will be super cool to see how everyone does it.

I stumbled on an option for those running DBW throttle body. Turns out my B9 S5 t-body bolts right up! It’s the same used on the 440hp (add 100hp for APR chip) RS5 so no problem with flow, and the hose adapter fits 2.5” silicone hose.

Looks good. What exhaust manifold are you using?
