Yes they use the OEM parts. That is one of the places I have wanted to look at upgrading but not having my car in front of me hasn't made it easy to figure out..
It would be nice to find out how much air cfm can go through Audi's pre-filter intake tubing. I am not sure how that is tested but I have heard people doing flow tests on different intake parts.
I am going to check into it..

Oh so simple
Take them out and test in cool conditions. That will tell you if larger ducts are needed.
This is from the Ferrea 2015 catalog.

Stock spec RS6 valves:

Exhaust: 29.9
+1 sizemm o/s
Intake: 27.9
Exhaust: 30.9
Unless Supertech and Ferrea are wrong, I believe the S8 and RS6 valves are the same size..
I have been confused since you said that stock RS6 exhaust valves are 27mm. I cannot find that information anywhere...actually I find the opposite...intake valves are 27.

In this video, watch closely to the reflection on the air box being pulled in by suction.

I don't have my car with me.
The engine is the original engine from a US spec 2003 RS6.
I don't know what information is correct pertaining to other engines. And I don't have my heads in hand. I am going to talk to Ferrea and get the biggest valves available for my RS6 heads. There certainly is lots of uncertainly about this subject...

But didn't you say that you where going to ship your heads this week? or have you already done it? (you have engine code in the front of one head where the lifting eye is)
If you have shipped them away already, then let your head guy Lee Schwartz measure them before you talk to Ferrea again.

Yes the holidays has slowed down everything. The heads are not even off of my RS6 engine yet.
If the valves we have bought are actually for a S8 then that works for me. I will keep my engine intact and find some S8 heads.
I am sorry but I am totally confused at this moment.... :/
I am not going to post anymore about this until I totally understand what is going on. I can't continue to relay second hand information.....
