So.. now I am gonna do the actual darintake sometime soon... the cone filter on 3 inch 30 degree bent exhaust tube.

I felt an IMMEDIATE change in my car!!! it was unbelievable what the little holes did!!!

Also I get a nice quiet "khhhhhhh" sound when I let off the pedal from my Hyperboosts :)

NOW!!! i am wondering.. what would happen if I drill my whole airbox with the little holes?!?!?!.........i am getting ideas :)

Advice? Comments?

i cant wait to do my intake

[audirs]

dont think ud want too many wholes. ud prolly start to suck in some unnecessary heat from the engine bay

[Kievskiy]

i drilled the whole lower part with holes and it did felt different:)

What you mean the whole lower part? like more than I drilled out? you mean the whole bottom pan of the intake?

Yeah.. and that is the thing I am worried about... sucking in hot air.

Any input??

The idea is to have the holes at the bottom to add airflow but avoid sucking in hot engine air. Another idea is to cut some slots out of the fender liner inside your wheel well as well. The B5 S4 has the same airbox, but already has the slots cut in the fender liner.

Cuttiing holes in the top is mostlikely un-neccesary because you are probably getting plenty of airflow already, and as mentioned above, you may actually lose power because of the hot air issue.

Here's a pic of mine. I drilled holes in the area that I thought would be the most-likely area to be pulling in cold air.

[Kievskiy]

well i dont have fender liner anyways so my lower part is all drilled :)

Question:

This intake modification is good for turbo'ed vehicles only?
Would there be any reason to do it in a non-turbo?

Go figure why Audi didn't just design the container to be ventilated in the first place.

I read the forums on the results. They look pretty good on paper, but is there any potential for damage because of the increased air flow?

Well, hope yours turns out as well as these other dudes.

If anyone wants the bottom of my airbox, I have already completed the darintake mod. It came off of my S4, which I assume uses the same airbox. I don't use an airbox anymore, and it is just sitting in my room.

All you guys have to do is pay for shipping.

I just checked the bottom of my air box while I was re-oiling my K&N filter and noticed 2 drain holes, so I pulled the box and drilled a few more holes. Ill let you guys know if I feel any difference as well. It would be a cool idea to run another duct or two into the factory airbox using some pvc piping and then throw in the cone filter.

[sempaipaul]

actually what I have been thinking... is a nice little intake ram in the hood :)

right where the hood has the little crease/fold mark... right there could make like a 1x2 ram intake thing.... i think it would look aggressive :)

Please no...

[sempaipaul]

Lolol.

No no.. non of the ricy crap... a really nice small one... ehh

nvm.. lol

as the box is now more susceptible to water, maybe 1 hole of matching diameter in the lowest area would be ideal for drainage.
Some 'noseeum' style screen may also help keep the larger particlles from entering the boc.(such as leaves).

Its a worthwhile mod dubbers have been doing for years w/ great results. Fresh air side only and your golden! makes a nice noise for cheap too, now just add a K&N

Holy merde, that's a lot of big holes...
are you no afraid to get crap in the box?

I want to try it too but wasn't gonna make the holes that big... what drill bit did you use?

I am interested, how much is shipping?

[mike's machine]

X2, how much is shipping?

[white fish]

is there any worry of the oil from the K&N damaging your MAF?

[lawnferie]

+1 i've heard this before and would like to know if it can be bad for the MAF and how?

[Stampy]

Oil from K&N's can clog the MAF sensor. Especially since so many people over oil them. Does anyone have any kind of dyno result showing and intake actually adding power? I know on the B5 it does nothing at all. Actually you lose power...just like when you do this to the 4.2. The Audi box is pretty good. Plus it keeps the heat out.

I did the half darrintake mod, IE holes in bottom and cold side and a K&N panel filter, recently when logging my 3- A6 vs my friends 3++ S4 with RS4 airbox we saw that I am pulling in 270g/sec while he is pulling only 250g/sec. This was a slight shock to him as he is a fairly accomplished tuner, his exact words were " I'll have to try that on my next S4 (he's selling his 3++)" Oh and results were at approx 4000ft altitude, Rocky Mountains

hey guys, as far as shipping goes. I am not sure sure. I can't imagine it being more than 10-15 dollars max. but i am back in Boston, and all my car parts are at my apt in Philadelphia, and i will not be back there until the first week of august.

ill inform you guys when i get back to my apt and whoever wants it can have it.

[Gigi]

Let me know when you're back home.
got dibs :)

when you say cold side, you mean your drilled the side of the box toward the passenger-side fender in addition to the bottom section?

[mike's machine]

I'm in boston, you should've brought it with you. lol

[Mantis]

Gigi, yup that's exactly what I meant, bottom and passenger fender side

[Ldiaz12]

Is this 100% safe like considering all factors like dirt and water ETC.?? Is it SAFE?!? lol

[Coors]

RESURRECTION!

It's only safe if you have an air-filter in place. Water intrusion is a slight possibility but, just add a little meth and your good to go.

Ok well heres the deal i just drilled a whole bumch of little holes into the bottom and passenger side of my airbox ... well i cant test it out because my car is in the garage and everyone is sleeping....... so idk whether its safe and yes i have the stoc air filter in place and what do you mean by meth

[4ringAR]

i dont know how this is beneficial for the A6 since we dont have vented fenders. i really want to do this but i also dont want to loose power because id be sucking hot air.

[Stampy]

Some people that do this on the 6, make a vented liner as well. Some even cut a hole in the liner as big as the airbox hole. I wouldn't recommend that method though. Rainy day leads to a SOAKED filter element.

I think Coors may have meant meSh...
Let us know how it works out for you...
and yeaah Holy resurection!!

[G Men 08]

i think we should all give this guy some rep!! he searched and that is a huge plus... i will probably try this little method here!! im always game for squeezing out some more power out of my little 8 banger!!

[Ldiaz12]

Ok here's the scoop I drilled six big holes on the passenger side fender and alot of little holes on the bottom of the air box and when I drove my car today you can deffinitely hear a difference idk if it accels faster but I'm still using stock filter I'll probably buy a kn air filter today and hope it all pays off ..... I'm just scared something might blow up lol

[Stampy]

Watch out with the holes in the fender liner. I have personally seen a SOAKED filter, that was definitely letting wawa get upstream.

[turbox2]

i did the mod. felt a little bit in lower rpms by the seat dyno... nothng spectacular.
sempipaul... do you hear any induction sounds? or just your dvs?

[Janus]

I was looking intothis a lot and am considering doing this to my 2004 a6 2.7T but I had a couple questions before I do anything potentially harmful to my car. Since the a6 doesn't have the vented fenders I'd have to cut out the holes into the fender lining. A good example I saw was here: http://www.audizine.com/forum/showth...8T-Air-Box-Mod but a bunch of you guys have made comments about water getting into your box and soaking the filter.

If I remove the lower portion of the box, cut holes into the fenderl ining on that section, and then use insulation tape and a mesh filter between the fender lining and the airbox (with that lower portion cut out) do you think that would be an adequate cover to help prevent water and debris from entering the box and damaging my filter or would it not make much difference moisture wise? Also, in general, those of you who have done this to your a6 - are you pleased with the sound it makes afterwards? I'm hoping it helps the car's sound somewhat, but the biggest reason for doing this is to help increase airflow.

Also as a thought before I do this: one of my next steps is to get a boost gauge and turbo controller to help monitor and control the twin turbos a bit since upgrading the turbos is a huge PITA. Adding a boost gauge and being able to have a bit more control over the OEM turbo's is more than enough for what I need and what I'd like for now. If you do this mod, would that potentially cause any harm or conflict with that new system when it is in place? If it does, I could just replace the airbox with anotehr OEM and get new fender lining worst comes to worst...

Thanks for takin the time to help out,

[Yesmar]

just do it. i cut a bunch of small holes and lines in our fender liner where the slits are on the b5 s4 liners, i then just cut out the bottom of the box,then had a screen laying around and hot glued it to the outside of the box. ive done it with all 3 of the 2.7T's ive had and never had any problem. i just stick with the oem filter they are good as is, no need to go k&n and worry about oil n the maf, and serviceing it ect. if i think about it next time i go to a pick a parts place that has a b5 s4 im going to snag the fender liner off it and see if it fits the a6.
about water, like i said ive been daily driving around with this mod done for years and never had any problems in bad rain storms and everything.

someone said they dont think it does anythin, or it actually decreases power, must have done it wrong. the darintake mod is the next best thing . its a lot better the most open element intakes as they suck in engine heat.

everytime i do this mod to a car i honestly think it has a LITTLE bit quicker throttle respons and feels abit smoother at higher rpm. no ive never dynoed a before and after but i know for a fact i dont loose power.

[Audi4.2]

so this is not recommended for the 4.2 model?

[Janus]

Thanks for the advice. I found a really nifty DIY for it here too to follow. Got the job done with my modded airbox and 27 new holes in my fender well. That plus the tune up and reattachment of a loose turbo intercooler hose and my car is running awesome. :)
