Are there any?

k&N or your skills in fabricating one

I cant find a K&N for the S6 on their website... do you know the part number or where I can find it?

k&N or your skills in fabricating one

Think I found them, do I need two?

We custom fabricated a cold air intake. Wasn't too expensive, but easily the most power from any mod. Using two large 5" x 7" cone filters, and ducting from front bumper (you can knock out the duct covers, they are removable, we took the front bumper off and you can duct right to the filters from those closed/unused air ducts).

Don't worry about secondary air injection, didn't get any error codes.

The car screams about 4500 RPM now, unbelievable. I have exhaust done as well, maybe combo of things is greater than the individual effects combined, not sure.

How about a pic of your setup?

That is great and I have read your posts, however I do not know anyone here in Vegas that can fabricate anything like this... Would this setup be available for sale with instructions?

According to an email I just got back from K&N customer support, they do not have any products that are specific to the S6. You *may* find something that works, but I wouldn't be very confident buying a part that doesn't officially exist.

i am considering this or BostonS6's solution.

Interesting... sounds good. Wonder if they can provide any pics? It'll probably be sucking in the hot air from the hood though...

i spoke to them a few weeks ago and they were out of stock. should have it now. sounded like a cone without ducting. going to call them to follow up. they didn't have a dyno, but said that it helped.

ask for marty, they should be in stock tomorrow. he knows me as john

Interesting... sounds good. Wonder if they can provide any pics? It'll probably be sucking in the hot air from the hood though...

marty said that the s6 stock is a cold air setup

Has anyone purchased the MSDS cold air kit?

How does it look/work?

i have a pic that marty sent me. i will post it soon

MSDS Filter

So the setup has its own heatshield? In the pic... it looks disconnected.

ordered these today. will have them on by end of next week. will report back

The stockers are built very poorly, are clearly very restrictive, and designed to muzzle intake noise....all fine if you like sluggish roll-on, run the stock exhaust and dislike intake howl.....However, I run a 2 X 3" LaBree system that flat rips, and was dying for some free-flowing air filters......The MSDS guys delivered bigtime, and when the guys at DC Performance ran mine on the 4X4 dyno for some tuning, they all agreed the sound(s) were awesome. Only other mods are SS Brake lines, Motul Brake Fluid, and Full-Time DRL LEDS.....and the Azenis 615 rubber which helps reduce the push a LOT.

Thanks for the feedback tailgunnner. i have the milltek and hope the filters match up well. Did the filter add depth and volume to the sound?

Hey guys,

After reading all the posts and looking at the picture from the replacement filter, I decided to purchase them and give them a try.

I am very happy with the response. The car sounds so much better and has a crisper throtle response. The air filters install in minutes and they fit perfectly in the stock air boxes. I am a very happy camper with the new filters.

I do not have before/after numbers on the dyno, ignore how much we really get out of them, but they do improve driving dynamics. When I downshift, the engine does not starve for air, upshifts quicker and does not drop off power as quickly past the 5k rpm mark.

I took the car up to the manufacturer set speed limiter like I do every once in a while. I did not get any CEL, or hesitation from the engine. The car pulls hard until the computer tells it not to run anymore. it took one day for the car to learn it could pull harder, the first day I did not feel a huge improvement. once the ECU re-learns the engine comes alive.

I thought I'd share some comments on the filters. They are a good purchase for the price, and sounds so much better.

thanks for the driving impression. i ordered them too and will have them on by the end of next week. so it is a diy job? do you have an after market exhaust? i have the milltek. as for sound, is it both from the engine bay and exhaust output?

Are they paper filter elements? I've heard bad things about oiled cotton elements. Like more dirt in engine = shortened engine life.

Ran oiled cotton filters on my BMW 325i, Audi TT, MB E55 with no issues.

Replacing filters? Yup, although I'm not sure how detailed of a process, but it can't be complicated.

The filters are very easy to replace. Here is a step by step:
1-open the hood- haha JK

-The air boxes have intakes going into the box from the front of the car. There is a small incision on the top of the inlet on the air boxes. grab a flathead screwdriver and push down the tab. pull the intake leads from the air box.

-Remove the flexible hoses going to the throtle bodies. The intake on the left hand side has a small plastic line going into the hose. As long as you pull the hose from the throtle body you will be fine; you just need to rotate the hose in order to get the box out.

-Remove the 3 screws holding the box together. (2 on top of the box and 1 in the side of the box facing the front of the car).

-Pull the box, be careful not to damage the cable going to the air mass sensor. you really can't damage it unless you yank on it. I mention this as a precaution. You really don't need to remove the air mass sensors. Remove the paper filter element. You will notice a plastic base where the paper filter element was pinned against. you need to remove this clip as it is no longer necessary. There is a total of 5 screws per clip. remove the base and save it in your storage room, you may want to keep them in case you ever install the paper filters again.

-install the new filters. (yes the air mass sensor is basically dangling with the filter. Don't worry, the air filters fit snug agains the box and there should be very little movement in the sensor once you get going.

-When installing the box back in the car. you will notice two (2) tabs on the bottom of the box, make sure you insert them in when re-installing the box.

-Once you get the boxes in place, you will notice that the box doesn't quite close as easily and you have to put some pressure against the filter. This is ok, you won't damage anything. Re-tighten the screws and re-install the air leads going into the box from the front of the car.

-When re-installing the air inlets to the box, you will notice little tabs sticking out on the front of the car. make sure you install the air leads in between the tabs and the mount. Sorry I don't have a picture. Once you pull them out you will know what I am talking about. If you still feel unsure about it, let me know. It won't take me but 5 minutes to get some pics and do a step by step procedure.


Hope this helps.



As far as the exhaust, I am considering installing the Milltek system. It is a bit loud, sounds amazing, but louder thatn what I would like. I am considering instead building a custom exhaust system that will not be as loud. I have removed the resonators in the stock system, and I am delighted with the sound. Yes, I know, cheap test. but I wanted to know how loud it could get.

Sorry forget to mention. The sound comes from the exhaust portion the most. You can hear the engine a bit more, but not much. When you step on it, the symphony is in the back. You will also be happy to hear that the engine does not drone inside the car.

I have run high flow filters before in many cars, and I send oil samples to blackstone labs. The only thing I have seen is a bit of an increase in the silica (sand) particles present in the oil. They are not high enough to cuase problems. You won't really have problems. I change my oil every 3,000 miles. so the risk to cause damage due to silica is very low. Yep, I do run synthetic oil mobil 1. I drive my engine, so I take care of it too.

So would you say this is a "must" for the S6?

Yes. I strongly recommend this upgrade. You will feel the engine breath easier and upshift and downshift easier and faster.

Thanks MO! My filters arrived today. Will be installed on Saturday and will report back.

I have the Milltek, should really purr with these filters. I have seen an S8 on youtube with custom filters, exhaust and chip. Sounded amazing hope these filters add some depth and throttle response.

Does one need to "oil" these filter with K&N filter oil?

I spoke the Marty at MSDS. He confirmed that this filter is already OILED.
Observation so far is that they are high quality. Can't wait to get them on this Saturday.

Thanks for the updates. Mine should arrive sometime next week. Really curious to see the filters' performance is once it is coupled with a chip and exhaust.

Post your feedback once they are in!

That will be about all that we can sensibly do to these cars. I will let ya know how the filter does with just the milltek and no chip (yet).

Mine should be here no later than the 30th. What will I get to do next then if this will be it???

You may have it all. How to you like the Unitronic Chip?

Love it! It was the first mod I did and would do it again without question. One thing to be aware of is that it is not going to be like a supercharger. People that think that getting a chip is going to add all kinds of power, and then they are disappointed when it's not what they thought it was going to be. I have chipped enough vehicles that I knew what I was getting and it turned out to be better than I anticipated. Better throttle response, longer shifts points, and elimination of the 155 "guv'ner".
I guess now a new set of shoes are in order.

Well, just make sure you have a good set of screw drivers handy... this thing was a PITA for the first time. Intructions really helped though. Will see if it makes any difference in the next few days.

Well, how does it sound with the Milltek? Feel any difference? I'm curious.

MO

Maybe just a little louder around engine bay, not sure if it is that much louder, which is actually good. The performance is barely noticeable, but it is there at low end and high end of the RPM spectrum. I'd recomend doing it because I think it ads something and takes nothing away. I will dyno the car this weekend with all my mods, so we will see what the numbers look like.

Agreed! I feel that it only made things better. There is a noticable audible change under load with the windows down. Sounds pretty cool actually.

I really did not want to do chip but reading that last post gets me on "I gotta have one" path.

Observations are the same here. I am going to do a chip mod next and am very interested in your dyno run.

The thing is I have no base dyno, and we all know how numbers vary from one dyno machine to another, especially given the altitude and temperature that I'm dealing with. I'm at over 2000 feet and already at 104 degrees here in Vegas. But it will be interesting to see none the less.

The combo of the La Bree 3.5" Dual System w/ X-Pipe Crossover and the MSDS Filters REALLY wakes this sleeper up...The Unitronic is perhaps the least potent, the exhaust the most, since the air coming in cannot come in much faster no matter what intake you have as long as you run that factory exhaust....It's just not designed for sustained WOT.

With my setup it is the opposite, I noticed the least gains with exhaust and filters and most gains with the tune. Milltek also has the X-pipe crossover, but it is just shy of 3". I can't imagine another .5" in diameter make the type of difference you speak of. If the OEM exhaust system was that constrictive, then we should all see great results from putting on any exhaust, but not me, nor anyone I know, and nothing I read about this says that's the case.

I DESTROYED the 2.5" La Bree at Laguna Seca last year. Literally the muffler packing blew out, and the pipes GREW 3" and smashed into the rear suspension. But I beat the car so hard that the brakes pads were gone at 4,500 miles and I am now on my 3rd set of tires (Azenis 615s are awesome) at 11,000 miles

Wow... I noticed the Milltek grows just about an inch when it is hot, but 3" is insane... wonder if it has something to do with the type of metal being used, or bad fastening.

The 2.5" pipes w/ H -Pipe and resonators was still too much back pressure....the 3" tubes w/ X-pipe and no resonators really, really flow lots better. The tips now only grow about 1/2" when very hot. The mounting is good and sound amazing.

Can send .Jpegs of the system if wanted.

Funny, I just noticed today that the stock exhaust on my'08 S6 grows about 3/4" when it's hot (and that's just from normal highway driving, not spirited driving....).

That's strange, I wonder if other parts of the exhaust close to the CAT are responsible for this... Never had an exhaust grow on me before, stock or aftermarket.

BTW, I noticed that I had some old Injen Air Filters on my gallery that I originally bought because they claimed to fit, but from the pics you could clearly see they were no match and have no prayer of fitting. That's why I went to Marty at MSDSInc.com to get the precise match and those are the ones you see us installing....so word to the wise, don't replicate my errors, and save yourself the hassle...get the right ones from the gitgo.

It's been awhile but here is a short hillclimb in L.A. with the MSDS filters, cat-back exhaust and tune.

Gotta get me some mods.
