Best Intake Option?

[AudiS4SD]

The stock throttle body tube that runs from the stock air box to the throttle body has a resonator device built into it that purposefully cancels out most of the supercharger whine. Simply replacing that tube with a straight more rigid tube (several different manufacturers make these), like the 034 reinforced silicone tube that I and many others use, eliminates that resonator. You will then hear the supercharger whine. That tube is a good investment and depending on construction costs about $100, sometimes less when on sale.

That mod alone, simply replacing the stock throttle body tube, may make all the "whine" you want, if that is what you are going for.

The more rigid tube is also less likely to collapse under maximum air draw during high boost, and will provide less air turbulence entering the throttle body than the accordion style stock part.

That clarifies nicely--thank you. I don't particularly need a full intake setup, just looking for some more sound. If you can use the 034 tube and still have the stock airbox, that sounds like what I'm looking for. This is the part, correct? 034 Tube

I know it's subjective, but how much louder is the whine? Does it still sound somewhat muffled or is it noticeable (obviously not as loud as a full intake swap)?

My bad, just went to the last post.

Sounds pretty good...not obnoxious.

Great explanations!

But the stock tube is more rigid than the 034's one. Correct? So, is it still better in this case? Or the best one would be made of carbon fiber or smth similar?

I just purchased a CTS Turbo Intake a few months ago on eBay for like 200 on best offer and installed it in under 30 min. It sounds really nice,

[vitopat]

I’m running the Injen intake. It’s built very nicely but I wish it was a little louder.

How did you "port" the airbox?

Keep in mind that all stated intake (diagnostic) HP gains from the manufacturers typically include stage 2 tuning to realize any HP gains

Is porting completely necessary or would that defeat part of the reason to do a closed setup?

I've had this exhaust pretty much since they released it and have never looked back. If you like supercharger whine, this is the best option IMO. Also, can upgrade to carbon fibre inlet instead of silicone.

Oops, I missed this post. Looks like you picked wisely anyways! Cheers!

Here’s where I am currently. A-little to much SC whine for me. I may go to a stock modded box like I posted above. Giving it more time

Its not necessary just folks wanting a-little more. One of if not the fastest car on this forums runs his airbox this way. This is a picture of loes

MSq5's setup, which includes a silicone inlet hose and AFE filter, is slightly louder even if you do not port the airbox. I am running this setup (without porting the airbox) and I encourage you to give it 1-2 months to break in before making a decision to port the box. The sound difference is subtle but it is there, and I have noticed that it seems to be getting louder the more miles I put on it.

The true cold air (exposed) intakes are too loud for me. If the silicone tube plus higher flow filter in the stock airbox is not loud enough for you, you can always port the stock airbox later. I do recommend that you have someone drive your car for a few passes by you when you are outside the car. The volume level is different outside vs. being inside the car.

Thank you for the information. I think I will go this route initially and see how I like it. If it's still not what I want, then I can move on to an open system. Plus, at least initially, it will be easier to swap to full stock before going in for service as well.

This is the filter you are using, correct? AFE 11-10121 Dry

EDIT: Actually, looked up MSq5's filter and saw he used a slightly different part number. Looks like the difference is dry vs pre-oiled. I think I read on here though that pre-oiled was not preferred. AFE 10-10121

Yes, I am using the dry filter. I think either one will be fine. I simply wanted to be able to take an air hose to the filter to refresh it. Didn't want to deal with oiling it. Never thought my setup would throw up TD1 flags at the dealership; I need to "feel out" my Service Advisor to see if the dealership would overlook this type of mod.

Makes sense; I will go with the dry filter. Regarding the dealer, I'm not sure it would even be flagged, but I think I would swap everything just to be sure.

The 034 silicone tube is reinforced. It is VERY stiff. I'm not sure what they put between the layers, maybe steel, but it is extremely rigid. The stock tube is thin walled, flexible, and can actually compress and reduce inside diameter when the supercharger is at high boost. The rigidity of the 034 is one if its benefits. It is so stiff you will struggle a bit in getting it over the throttle body and the air box ends, thinking it doesn't fit. It does, but you have to work with it.

The oiled cotton gauze one flowed considerably better than stock in a comparison test in another thread, (see link) so I selected that, but if the dry flow version flows somewhat less, that may not be enough difference to really matter.

Yep, my 17 year old suggested spraying some WD40 on a cloth and wiping the end and inside lip of the silicone tube after I had struggled for 10-15 min. -- BINGO! I'm not sure when we would have gotten it on, otherwise. Mad props to him! We werre successful first attaching it via the clamp to the air box, then working it into position on the intake manifold.

So I went ahead and installed the 034 tube + AFE filter this morning. There is ZERO change in noise, not even a little. Not what I was looking for in a closed system. I figured from the comments here and the fact that the stock tube has a resonator that I would at least get like 5% increase in sound. Nope.

Guess it's on to open intake...

I know it's disappointing AT FIRST. As I said, I encourage you to give it at least a month. The sound of mine has noticeably increased over the last 5 weeks. Also, have someone perform a pull in your car while you are on the side of the road. If you don't like it at a month, pull the airbox out and port it.

[Maple Leaf]

Might be a noob question but if you already have an upgraded inlet tube and filter (stock air box) and you eventually want to go stage 2, does it require you going to a full intake or porting your stock one? I’m not a fan of supercharger whine so I want to weigh my options.

Nothing requires upgrading anything about the intake.

No. You can run Stage 2 with a completely stock intake or any degree of modification to the intake. There are cars here running 10 second quarter mile on this platform with the modified stock air box and upgraded hose and filter. I'm pretty sure those cars were deep into the 11s even before cutting holes in the airbox. It flows well to considerably over 400 hp. Gains from modifying the stock air box or other aftermarket intakes are real, but modest.

Yea we'll see!

So, what changes in the setup that causes the sound to change? I don't see how a filter getting dirtier from day 1 and the tube not changing would result in an increase in noise.

Thank you! I’m going to give the AFE filter a shot.

I have no idea. All I can do is share my experience (about 5 -6 weeks in at this point). If you prefer more whine, the open intakes seem to certainly provide that.

If you decide to go open intake, I'd take the 034 tube and filter off your hands. Just let me know.....

For any of you using the stock box setup - I’ll be selling my afe filter that’s been used for about 2k miles when my APR gets here :)

Switching from OEM to AFE filter instantly gave me a lot more SC noise, but I already had a ported box.

Yea my AFE filter, though dry setup, did absolutely nothing combined with the 034 tube. Very strange.

Somewhat off topic but is there a filter box setup that makes it easier to replace/clean the filter when needed I find it a bit of a pain to get to the filter. I don't care if I have to get one that has a lot of whine but I want function rather then forum.
