RS7 Intake Part Compatibility with S6 Info Thread

[RedSoxRS]

I recently went APR Stage 2 with my 2013 S6, looking to upgrade the intake and cooling as much as I can with OEM parts.

Starting with the intake, it appears that the RS7 inlet pipes and RS7 airbox are compatible with the S6 turbos. Any input on compatibility appreciated!

I'm attempting to compile a full part list, any help or input here appreciated!

I'm trying to get all the facts in one place for myself and for others in the future. Thanks for your help.

Im pretty sure that the intake pipes are slightly larger on the RS7 than on the S6/7 as the turbo housing is larger - however Im also sure I seen a fairly recent post from someone who had done this modification recently. Try using the search function at the top of the page.

As an alternative, you could just save all the hassle and go with an all inclusive kit https://www.revotechnik.com/product-...-intake-system

[RedSoxRS]

Thanks for the input. I am looking to stick with OEM hardware on the intake side for now, so the Revo Kit would be out for me.

I have used the search function and have found information scattered everywhere, hard to tell fact from speculation. Looking to get the facts in one place for reference.

So I guess the first question is whether the RS7 intake pipes can be used on a S6 turbo? I will continue to look into this on my end.

[jsmonet]

I thought pricing on the OEM kit was not far off at all from the Revo kit, which IS the OEM kit with the stepped inlet hoses already provided as well as a different filter.

[dannybear]

The rs7 pipes are larger diameter than the s6 however the gasket that attach the pipe to the turbo's is the same for both cars therefore it's quite possible the rs6 pipes fit on the s6 turbo's.

[RedSoxRS]

Is anyone able to confirm that the larger diameter RS7 intake pipes can or cannot fit on the S6 turbos?

The Revo intake is a nice option, but I would prefer not to step down the hoses if possible.

I would like to know as well. I have been trying to get my hands on the RS7 intake hose 4G0129616A, but it's back ordered. I think it can probably be installed in the S6 airbox without trouble. I will just cut some holes in the housing to match the RS7 airbox. If the metal inlet tubes for the turbos from the RS7 use the same o-ring, it stands to reason that they might fit the S6 turbos. But the inlet tubes are not cheap. I would hate to order them only to find out that I'm stuck with $580 worth of metal tube that I can't use and can't return. I might be willing to go for it if I could get my hands on 4G0129616A.

I know the tuner companies really want to sell you downpipes, but the RS7 uses the same downpipes as the S7 / S6. Yet the RS7 does have a different intake. IMHO I think the intake is probably more of a problem than the downpipes.

This listing says they have 2 available. HTH

I tried to get some parts from that ebay/audi dealership recently, order ended up canceled because they didn't have the part in stock. Here's a used one from Europe. http://www.ebay.co.uk/itm/Audi-A6-S6...wAAOSwknJX09pX

The hoses are better they are silicone. Fits really well and looks OEM if you pull their logos off it

From the earlier topics and info around, i remembered as far as intake goes, stock box is perfect (performance wise). RS6/7 box (additional holes) doesn't give you extra performance, they might even do more bad under heavy temps (warm climates and high engine bay temps).
There might be a gain with the dual airfilter kits, but some say not, some say they do (there was a post on rs246 forum about a dual test, two cars, stock and dual filters, tests pending as they wait for warmer weather....UK).
Imho, cheapest bang for the buck is replacing stock filter with a K&N filter or simular filter as they are less restricking, but keep the filter clean ;).
Only gain might me throttle response :).

More interested in true cooling the engine. Afaik the designed the engine to heat up fast (or maybe just a side effect of design, turbo's between engine), witch is good, but imho you need extra cooling once on temps so you don't enter heat soaked engine and power loss.
A cheap fix/solution isn't out there afaik....maybe meth kit most effective?

[Dasquade]

Afaik most silicon tubes are too hard and not flexible enough (short tube/heavy moving engine). Read post about popping of tubes, but might all be about finding a good isolated, strong yet flexible kind...

[jsmonet]

The silicone hoses that come with the revo intake suck. They're slightly too long and getting everything together is a pain if you don't carve a slope into the step on the engine side of the hoses so you can shove them up the tubes a bit more. I can't change my air filter, or even service it, without going through another nasty fight with it. When the time comes I'll either sell a kidney to go rs6 turbos or buy the pipes and factory accordions

What is the current market pricing on a kidney?

I'll be honest I thought fitting it was difficult but I'm useless at anything diy so I presumed it was just me. Had to go to shop to fit shamefully :-( they did it in 5 mins

I really should be able to get at least 2 RS turbo kits. They're good kidneys!

You'd get more for 2 kidneys, but the outcome is unfavorable

Hi,
Bought all parts to do the airbox plus intake pipe swap to upgrade to RS7.

One question though: intake seals (#29) seems to be same as S7 but thought RS7 pipes were larger?

Thanks for your help!

I think your information is mistaken, the whole allow more air to enter the box which allows it to breath better any time you take away a restriction it is going to perform better.

I found this out when i had rs7 turbos on my s6 and had to drill wholes in the air box to allow for it to make the appropriate gains, the data on the dyno does not lie. I would suggest you talk to the people who told you this airbox is perfect because clearly they don't have much experience with the c7 platform.

Sweet, then it sounds like I guessed right. I used a hole saw to make openings roughly equivalent to what is on the RS7 box. I am running the RS7 filter and pipe assembly on my S6 box.

[Julius_855]

Cool! Did you also change the O rings?

Still i'm skeptic if the warm engine bay doesn't make things worse compaired to closed box. I'm not taking about 'cold controlled' dyno tests...but real life situations. Thinking of in traffic, stationairy...we all know under the hood temps can be extreme warm! Simply cant believe sucking warm engine bay air helps things :s.
Waiting on apr to release their intercooler and maybe custom solutions to extract heat out of the engine bay.
Untill then i stick with my closed stock airbox and k&n filter...
Any suggestions how to cool down engine bay temps are welcome, but an other dedicated topic might be more usefull :).

Awe thought the same thing look how that turned out.

Apr also did testing and saw that an open filter has the highest gains you can look up the old thread.

Tought i had seen topics that kinda disagreed with that. Once again...real life data versus controlled dyno pulls i refure too. But also, but maybe my simple logic, anything warmer then ambient outside air cant be better (yes no direct super hot parts bear the intake but never the less close by and i wonder what the actual temps of air it is sucking in...i guess around 50-60 degree euro temps. Kinda makes me wonder if it all comes down to simply the additionel volume of air (hotter or not), meaning the stock airbox is restricted and maybe a secundairy inlet (fed with fresh outcar air) would be a better solution? No mather what, not trying to get a point, just wondering :).

[sciblades]

Dyno rooms are much hotter them ambient your argument is not logical.

No one's intake air temps have gone up from going to a open filtered option, with that said in theory a closed box should be better but, no one has make one that is better than the roc-euro option

[Dasquade]

....so it all comes down to extra air (weather it is hot or cold air)? :)
And yes i understand we are compairing apples with oranges here. Stock airbox, be it fully closed or semi open rs one with one single airfilter versus dual dedicated per turbo roc-euro. Hotter air or not, double airvolume....

[Dasquade]

But this was kinda my point in this topic...rs box versus stock box. Guess you kinda understand what i mean.

Guys..

This thread is not aiming to discuss efficiency of the mod but sharing fitting info. There are a couple of other threads discussing relevancy of this mod.

So... does anyone knows if O'ring are the same and if, could be reuse as they seem fairly expensive.

Thanks.

If you are talking about the rubber grommets in the frame rail then yes they should be interchangeable
