Best Intake Option?

[freed]

I have been looking a the various silicone and carbon fibre intakes for my 2014 S4.

Wondering if people a any opinions regarding performance, sound, etc. from the different manufacturers?

Thanks in advance,

Heard this one is good. Waiting for sale or if somebody decide to sale it.

That is a petty nice looking intake and at a reasonable price.

One question/concern though..i have read that that the accordion type bends do not allow as much air flow as smooth ones. Thoughts?

[BlackJon]

I got Roc Euro Intake and I love everything about it.. the sound and easy install

Drive it like you stole it 😎

[Johnnah_Daia]

+1 for Roc-Euro
Started out with an Eurocode just because of price, but then moved to Roc-Euro 6 months later and love everything about it! The sound of the supercharger can be a bit obnoxious at times...but I'm so dam addicted to it lol

If you like the roc euro just get the cts turbo. It is identical except has better heat shield mounts to the car and a nice little billet emission filter attachment. Plus their customer service doesnt make a habit of lying to customers about stock levels and stringing them along until threats of chargebacks are made

All of this is correct and ECS offers some really nice pieces also. Screw ROC

I agree with Mike and 14S4GWM. I have the CTS intake and love it. I would also recommend applying a rubber hose to cover the air condenser line. It does have a tendency to rub under vibration

I have the ECS carbon fiber intake and couldn't be happier.

Bang for buck just drill some 2" holes in the lower half of your factory box and save your money.

Best option for anyone with a warranty. Stealth mode

The stock intake is about as performant as you’re going to get. Pull the top off the factory box and go for a spin to get an idea of what it’s like to live with copious supercharger whine... Some dig it. I find it annoying honestly.

[brs2c]

The better the heat shield, the better the intake. Hot air IS the #1 performance issue on these cars. This is why some of the fastest cars run a modified versions of the stock intake.

I'd like to go the modified stock airbox route, but looking at the price of used stock airboxes and the idea of irreversibly modifying mine led me to an aftermarket intake system. If I could find an OEM airbox on the cheap, I'd likely go that route.

Slightly off topic, but recently for shits and giggs I ran the stock intake tube with an aftermarket open element filter (i.e. not with the stock airbox), and there was as little supercharger whine as if I had the complete stock intake system installed. I guess all of the silencing is done by the tube, not by the box. I was surprised.

We are just talking about one 2-3/8" circular hole in a molded area in the bottom of the stock air box that coincides with a circular pattern located there. This modification is invisible. You could plug it later, if you don't like it. Some drill more/larger holes. I don't think that has been shown to increase flow very much.

Just do that 2-3/8" hole, add a high flow pleated filter of your choice, the 034 silicone throttle body tube and call it a day. No aftermarket setup will flow better and is likely to be worse if it does not isolate the filter from engine heat.

And, yes, there is a resonator built into the stock tube that is used to cancel out most of the whistle sound.

Love my CTS Turbo intake.

[TTreef]

Looking at intakes currently. Will the CTS mate up to an APR ultracharger without a problem, or would additional jerry rigging/parts be needed?

[ModdedEuros]

CTS Turbo is our top seller especially with the sale right now. A lot of the open intakes are very similar.

Will it work with the APR Ultracharger? From the looks of it, I would have to cut the tube..

[AudiS4SD]

Looking to get an intake soon...with a couple questions:

I think ECS will be too loud for me (don't want obnoxious when just commuting) so I think that one is out. Roc Euro is out due to their horrible customer service. So I'm currently eyeing CTS vs. IE. Thoughts? Does metal vs. silicon tube make any difference on an otherwise stock vehicle? I THINK the CTS intake is a bit louder than IE from what I've read here, but not sure. Every ear is different, lol.

Also, newbie modder question: once the intake is installed, do you have to mess with the ECU at all for different airflow/fuel tuning or just plug-and-play?

[Morritse]

The fastest S4 on this forum (I guess it's an s5 but same thing, loe's)
Used a ported stock airbox and silicone inlet hose. I honestly think that's the way to go, plus no emissions bullshit.

Pretty sure the ECS will be one of the quieter ones since the filter element isn't exposed like the others. Heard from other members that the videos make it seem louder than it really is.

Is the carbon fiber ecs intake louder than the plastic one?

I am confused about one thing: People keep saying that isolating the intake from the hot engine bay is the most important thing (makes sense).... however, this picture seems to show a cheap looking piece of metal to separate the intake from the engine bay with plenty of space to allow HOT air back into the filter... what gives?
Thanks

[MSq5]

The stock air box is a true cold air intake system, drawing air from the outside through the front grill. You can increase flow potential by drilling hole(s) on the bottom of the front headlight side of that box. This is away from the engine.

The stock filter flows quite well, but a study posted elsewhere here shows that some aftermarket filters like the dual cone aFe Pro 5R flow better, and that the stock throttle body tube can be improved upon by using reinforced smooth sided tubes, like the silicone one made by 034.

There are guys like one of our moderators here that are running in the high 10 second quarter mile with the stock airbox set up this way. Those are the most highly modified cars. They must be making over 600 horsepower to produce those numbers.

I think every other approach is interesting and may produce different subjective sounds, and have different visual appeal, if that is what you are looking for, but I seriously doubt that they improve on actual performance compared to the simple air box mod, stiff, smooth throttle body tube and a high flow drop in filter in the stock airbox.

Our intake will be on sale soon ;)

I just bought the ECS with CF top. It’s still loud, is open underneath except for heat shield. If we’re talking the same thing I can show some pics.

I had the roc euro too and I do think it was indeed louder. But if you stock from ECS it will seem very loud.

I like the USP motorsports one. It sounds great and isn't terribly expensive.

Not entirely sure. I'm somewhat familiar with the IE guys though and I think I heard word that a sale will be happening during Labor Day Weekend.

What stats you are getting with your Intake at stage 1 vs OEM?

settled on this:

[XLR8 Craig]

APR has an open element intake setup for these cars as well!

With a 7" filter and a carbon fiber heat shield to keep IATs down, this intake is a great way to help the car breathe easier and gain up to 17hp!



We have them in stock ready to ship! You can find them on our online store here.

Feel free to send us a PM for pricing!

Charts show Stage 2 WHP from 362 to 383 with the stock intake being swapped with our intake.

Unfortunately I don't have anything stage 1 related in terms of charts but it'd be damn close to that same number difference.

Closed: better IATs. Which is a huge deal on these cars. Also, if you use the stock airbox, you won't get any shit trying to get through visual inspection.

Open: more flow, better sound, easier to clean filter, looks better (to most)

Personally I think closed it better just due to how big of a problem IATs are on our platform.

So if I want to get more whine, can any of these intake systems get covered by the stock airbox (but this probably defeats the purpose) ? Or, to get the whine I need to go full open and reinstall stock intake before going to the dealer (which I know some on here do)?

If living in a hot climate like NV, would going open intake just cause issues in the high heat?

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.
