Air Intake Suggestions

[thestigx2]

So I'm looking into finally changing my air intake. I'm just not sure what would be best, a cold air intake like the Carbonio's or get one of the AFE kits. Some people had mentioned to me just to make one out of scratch but I tend to break things when I do that, so I just want to buy a ready to install kit. Thanks!

Carbonio with 3.0 snorkel and beefed up heatshield:

[LINDW4LL]

Keep the stock intake.

Keep the stock intake.

Agreed. The 3.0 snorkel with the OEM air box might help a little. I just posted the pic with the Carbonio because some peeps insist on replacing the OEM box.

stoke + AFE dry filter + Blinktek upgraded heatshield.

Is there any mod I need to make for the 3.0 snorkel to fit? And why keep the stock one? Just the aftermarket ones are a waste of money?

Where can I get the heat shield? It is it custom made myself kind of thing?

The stock air box flows enough with low pressure drop up to 400 Hp, "Cool" air intakes are just the opposite. The stock paper media, Mann or other German filters flow the most with the best filtering efficiency on the street. Change every 6 months or annually. A K&N filter will flow more with less pressure drop, but the filtering efficiency for very small dirt particles (the most abrasive and damaging,) is not as good as an OEM paper filter. Avoid using Fram or other thin depth filters.

+1 for stock box.

Every Audi I have ever owned had a stock box that outperformed any cone filter (provided a good quality filter was used).

Most of the aftermarket filters (think K&N) are just pure junk.

I agree with stock airbox, don't waste time or money on anything else. It is time and again proven results the stock setup works for 80% of applications. If you want extra diverted calve noise you can cut some holes in he box and get the same sounds you would from a CIA

Where exactly are you saying? I have an a4 b6. Are you saying drill holes like on the filter box top?

You will have to grind a little off the bottom side of the 3.0 snorkel flange to get it to fit. Does it make any real difference? I don't know. I have read several posts that indicate "butt dyno" gains. I will have some conclusive evidence one way or the other later this week. I ordered a used 3.0 snorkel from ebay for $20. I will log the MAF g/s with the 1.8T snorkel and then repeat the same thing with the 3.0 snorkel to see if it helps any at all.

Stay tuned!

^Im curious to see the results.

I will be looking forward to it! It would be interesting to see how it performs.

Search Darintake Mod. I've ran it in my Stage 3 2.7 and am currently running it in my 1.8 USP.

If you're on k03 keep stock air box.

If you're big turbo and top mounted you need to make a custom intake.

No need to change the intake when you're running a k03.

Yeah I googled that one and it said sold already that's why I asked...

as indicated by the ad, the seller is the guy who makes them, not some random seller -- send him a msg and ask if he's still making them.

Ohhhhh, ok I will shoot him a msg, I thought some big company made them lol thanks for the heads up

Stock air intake is the best. Like others have mentioned here, unless your going bigger, way bigger turbo/hp your wasting your money and in the end you'll get no benefits. In most cases you actually lose instead of gaining.

[Fast4esT]

You can cut holes in the lower portion of the box, below the filter

[slark]

So you're saying the k&n can actually give you loses on stock tune/turbo?

[alien_brain]

K&N oil can get on your MAF and screw everything up. not a good thing.

[texasboy21]

A high flow panel filter and turbo inlet pipe make for a noticeable gain on the butt dyno.

[slark]

If the k&n is a no-go, what about the dry piper cross or afe filter?

Edit: I used the search(what?? No way!) and read through some old threads and articles and of course, diagnosticator and old guy provided the majority of science and reason.

OP, the best filtering filter(what a filter is made for) is going to be oem. Mann would probably be the brand to go with if you don't want to pay for genuine. It filters the best and it barely falls behind the aftermarket in flow. In the b6 Chassis the air box and filter element are actually really large; nearly twice that of say a mk4 vw. Using a stock filter until you're running a big arse turbo is going to be the best for your engine. I'll actually be replacing the k&n that the po put in with a Mann in the near future.

Hope that helps!

Is that a 3" MAF housing? I also hate how it gets very tight in there with a TIP.

I've ran a K&N filter on 2 B6s for over a year without any problems. One has stock KO3 other has a Frankenturbo.

I was looking at my Frankenturbo TIP yesterday and thought about the 3.0 snorkel and don't think it would fit. The TIP is very big and higher than the stock one.

I'm also running a 3" MAF housing and the Frankenturbo TIP and I have the OEM 1.8T snorkel in place. The 3.0 snorkel doesn't protrude downward any further than the 1.8T one so I think it's gonna fit. I'll let you know once it arrives.

[Luxus Panzer]

I'm also running a 3" MAF housing.

Is this 3" MAF housing a plug and play part with the stock MAF guts?

If so, what is the part number and what year and model did they com in?

also... how wide it the I.D. on the stock MAF? 2.5??

The OEM MAF housing is 2 ¾". And no the 3" housing isn't "plug and play" with the OEM sensor. You will have to work with a tuner to rescale the airflow readings for it to function properly. If you are running a K03 there really isn't any advantage to going with the 3" MAF housing. The 2 ¾" will suffice just fine.

[old guy]

I just took a few crude measurements to see if the snorkel mod gives any appreciable difference in opening size for increased airflow. The choke point on the OEM 1.8T snorkel is approximately 2" x 3.5" which gives 7"² of opening. A 2 ¾" MAF housing is 5.9"² so all things being equal the snorkel should not pose any restrictions.

Now consider a 3" MAF housing is 7"² of opening which would lead me to believe the 1.8T OEM snorkel should also be a good match for the 3" MAF housing. The 3.0 snorkel is around 12"² of opening so it should be capable of flowing way more than anything a 3" MAF housing can pull.

I know that there is a lot more going on than just airflow through an opening but on the surface I'm guessing that the 3.0 snorkel isn't going to do anything different than the 1.8T snorkel. I guess I'll know for sure in a few days.

Stay tuned!

That is the stock MAF. It is a bit tighter, but the Forge TIP is quite a bit larger in diameter through the middle section compared to the stock TIP.

^^^This and it won't collapse under increased vacuum of higher boost levels like a stock TIP will.

Uhh, cutting holes in the box AFTER the filter are only drawing in unfiltered garbage into your motor. Not smart.
Also cutting holes in the box is going to draw in extremely hot air from the engine bay / turbo etc.. not smart.

Keep it stock unless you're going big. How many ppl have to say this before ppl stop trying to "mod" their intake smh.

Yup, I just bought the 3.0 snorkel and a heat shield wall and also a Mann filter and I think I should be good that way. I'm tuned but I ain't going big. I was getting 1,200 CFM's with a K&N drop in and my 1.8 snorkel. Not sure if the CFM's will increase with the 3.0 snorkel. I will also do a reading of how much air is going through.

About eight months ago I went against all the advice, logic and opinions on this topic and decided to slap a cone filter on my MAF. I figured since I was running one of the best intercoolers for these cars that the additional heat would be a non-issue. As of last week I decided to put the stock air box and duct back in. I had to do a few modifications to fit a 3” MAF and block off the hole for the air pump, but I can say that I am more than happy with the outcome. It may just be placebo effect but the car not only sounds better (turbo/DV noises were starting to get annoying) it also runs better, and I even think my mileage has increased slightly. I am going to take a new log to see how the IAT’s have changed and hope that this will also help to reduce my timing pull.

[GTA]

Thought about going K&N and or aftermarket intake, etc. after I did a Stage 1 flash but didn't. Just bought a fresh Mann filter and my wallet's better off for it.

The airbox besides being a true cold air intake, also has a flow straightener before the MAF. When I experimented with a cone filter on the MAF I noticed a much rougher idle, even before the filter would heat soak.

I'm planning on taking some measurements this weekend and see if I can fit an acoustic flared port horn inside my airbox to see it it will make any difference. Obviously the OEM 2.75" straightener will no longer fit with the 3" MAF housing.
