picked up a APR CARBONIO B6/B7 S4 4.2L COLD AIR INTAKE. going to retrofit it to my car. also have my friend making my custom made carbon fiber intake piping from throttle body to apr intake. also make a carbon fiber mass airflow sensor housing.
heres the intake…
lulz
you will probably want to sell that. And ask questions about mods before you buy them to help you avoid walking to anymore sharp sticks.
ha i have read the threads about the APR CARBONIO B6/B7 S4 4.2L COLD AIR INTAKE on here and audizine.
bottom line is that the apr performs better while car is moving. but if your car is idle it heat soaks alittle more than stock box does. apr retains the stock air flow inlet from front grill. half of these people are comparing stock box to plain old open filter with no enclosure like apr has. so of course there runs are going to show better times with stock box vs unprotected open filter just soaking in all that exhaust manifold heat and whatnot.
bottom line i got it for $100…should that tell me something? probably but im going to rework this thing. full carbon fiber en closer. not just the top. plus full carbon fiber intake piping and intake mass airflow sensor housing. it will retain front grill air flow tube and SIA port. now please dont tell me people think the the stock box with shitty recycled plastic that audi used will deflect heat soak better than carbon fiber.
but i do appricaite your input…sakimano. i however am destine to make it work and perform better that stock air box. ill be doing before and after data logging and dyno pulls at CBtuning in PA.
Ill also be working with redline speed worx in nj since there 5 min from me. they will be helping me with this car.
no actually, that’s not the bottom line. The bottom line is that the stock box is pressurized, sealed, and is all around very well designed to make your NA car go faster. The Carboner is none of those things.
who are these ‘half of those people’ you are referring to? I am one person who gave you some good advice. You chose to convince yourself that I am wrong, and that is your prerogative. It is your right to be slower.
Enjoy the car, and good luck.
and that is why i said i appreciate your advice. im referring to threads i have read on audizine.
your right The bottom line is that the stock box is pressurized, sealed, and is all around very well designed to make your NA car go faster. but that is what i want to do with the apr as i said.
“im going to rework this thing. full carbon fiber en closer. not just the top. plus full carbon fiber intake piping and intake mass airflow sensor housing. it will retain front grill air flow tube and SIA port.”
i bought this mainly for the top carbon fiber piece to use as a guide to build a full carbon fiber encloser under it.
it will essentually be a stock air box made of carbon fiber. it will not be using the open element filter as they already went in the garbage. the custom lower conpartment were making of carbon fiber will be seated to hold a K&N drop in filter which i am currently using in my stock box
carbon fiber handles heat better than plastic…and this engine puts out mass heat in the engine compartment. thats my reason for doing this
We should introduce you to troyguitar (airbox) and squiddy (intake and differential) and all the other guys who decided to ignore the experience and advice of those who went before them, and to instead devote themselves to reinventing the wheel…on a part that will do next to nothing for performance on an all motor 4.2 Audi.
im not trying to start an argument or get on your bad side…im doing to lower heat soak consumption not to gain HP. but hey you are probably right and im not going to fight it. this is my hobby and what i love to do is work on audi’s. its trial and error.
what are some things to help the 4.2 belt driven V8?
Lovely thread. I’ve never been one for cosmetic modifications. Perhaps that’s because so few make a car look good. You’re finding the right combination. Well done
Thankyou
I like the idea of replacing plastic pieces with carbon fiber, it’s something I have been wanting to do on some pieces in my own car, but I would hesitate with replacing anything that could negatively affect performance. I know you said you’re doing the whole air box etc etc
It certainly looks as if it will be an enjoyable project. I hope it all turns out to your liking. Best of luck!
Is it possible to remove the belt driven fan and make it all electric. That fan has to be taking some ponies away. Plus I think my fan clutch it failing on it and is stuck grabbing. It sounds like a jet.
JHM kit
From another forum…
[i]Would this fit on a 4.2? If so, pissed i just spent $400 on a new clutch fan bearing assembly 
JHM reply: Yes it requires little to no changes to fit. We have done them in the past. We just don’t have any new info for this kit directly on the 4.2l but it will work, the old kits we used to sell fit great. We would be more than happy to help out anyone who bought one for their V8 if they have any questions or dealing with any slight differences in the install.[/i]
Thanks v8a6
would a custom accessory belt be needed with the belt driven fan gone?
It would obviously make the stock belt to big with the fan being bypasses
The B5 kit doesn’t come with a shorter belt so I would assume that you reuse the current belt and just don’t put the fan or fan clutch back on.
The B5/C5 2.7T kit utilizes the factory belt and allows complete removal of the mechanical fan assembly while their block off plate takes its spot. It looks like there’s enough play in the belt tensioner.
From their install pics
interesting…anyone have this? is it worth it. does it help acceleration alittle?
I just ordered some more goodies for my car…
also just got car back from redline speed worx, they did some maintenance things.
maintenance wise i got NGK Iridium Plugs, fresh oil change (audi oem oil filter and 8Quarts of motul 5w40, fresh brake fluid flush (ATE Super Blue Racing Brake Fluid), power steering fluid fush and refill with audi oem fluid, and a flush and fill of Audi OEM G13 Coolant.
Im also doing my custom Magna-Flow exhaust this weekend. I have a tig welder so this will be fun
my lower control arms are shot too…
should i got with Febi Bilstein full control arm kit or 034 density line full kit kit?
Vince, nice car great choice.
The ECU tune helps take care of this. The TCU tune plays a roll as well but, its the TQ converter lock up that plays the bigger roll in lag.
thankyou
