Mishimoto B9 S4/S5 Catch Can R&D Thread
Hello AudiWorld!
Nick here from Mishimoto! I'm starting this thread today to let you guys know that we are embarking on an engineering journey to create a direct fit catch can kit for the B9 S4 and S5. We just got our very green loaner in the shop yesterday and Jason was eager to get started!
I'll be sure to keep you guys posted on the progress. Also, feel free to shoot me any questions, comments or concerns you might have!
Thanks,
-Nick

Is there any demonstrated reason to have a catch can on this car? what problem are you solving?
On my Mk7 Golf R, the catch can was totally worthless, it just filled up with water mostly. Seems that modern engine designs have made the device pretty pointless but that didn't stop 10 manufacturers from coming out with one for that car....

What’s a “catch can?”
#4
My understanding is that it's a device that tries to separate oil / liquid from the blow by before it gets recirculated back into the intake. The idea being to reduce carbon build up on the intake valves for direct injection engines.

Looks like this was crossposted to both the B9 S4 & S5 forums, so I'm copy-pasting my reply to S4 thread here:
Hate to break it to you guys but the B9 S4/S5 already has an oil catch can/fine oil separation+recovery mechanism right from the factory. See pages 20/21 of this doument: https://www.yumpu.com/en/document/vi...5/ssp655-wg-en
Would certainly welcome clarification if I am missing something, but it seems to me that there is zero benefit to bypassing the factory system, and no need for an aftermarket oil catch can on this engine. Wouldn't mind seeing more pics of that car though...that is a serious green.

Presence of oil does not confirm rate of accumulation or demonstrate a need for a catch can, as I said, catch can always filled with water and very little oil.
If a very small amount of oil blowing by was a problem they would have just made the stock system better, but I am certain its not a problem.
But by all means keep trying to sell product that people don't need to the others who will gladly buy this because they believe the marketing. Just voicing my opinion.
