Is there a way to fab a cold air intake on a s4 turbo with the following conditions?

1) retaining the washer fluid reservoir.
2) retaining the air pump silencer.
3) allowing space for a future fmic.

Thanks

 

screw cai ... make a good heatshield. Take your time and the difference in air temps will be minimal.

 

just wondering...
cai works by drawing in outside air.
What does a heatshield do to decrease air temps? A source of colder air has to be coming from somewhere...

 

You seem to totally misunderstand what a proper cold air intake actually does. The idea is to prevent any engine bay air from entering the filter (a heat shield) and provide a big enough path for outside air to be sucked in (a duct). You have to have both or you might as well have neither. A duct without a heat shield does nothing to stop hot engine bay air being sucked in, and a heat shield without a duct will either restrict airflow if it doesn't leak around the edges or do nothing if it does.

 

If the washer fluid cannot be saved... could I modify the sub zero assist fluid tank to be used as my source of washer fluid?

 

Some models came with a bigger washer reservior on the opposite side of the engine bay. There's a hole there for the filler neck to come up through. You have three options for that location: try to find a genuine left side reservior, adapt the reservior you have, or buy an aftermarket generic reservior/pump. You'd need to swap the piping over and extend the wires.

 

i forgot to mention that setup should include a duct, i have my ftp's out and i made a cai headlight cover haha. w/o ducts or anything its only abit better then not havin the shield.

 

I have an S4 turbo and I am retaining the washer fluid reservoir, I have a huge FMIC piped with 2.5" on the hotside and 3" on the cold, but I dont have, and cannot remember where the silencer goes.

Anyway, I have made room for a 4" mandrel bent cold air intake. I am feeding my soon to be GT4088 from under the pass headlight. I did this by removing all the wiring, the brake duct, and the washer res and then cutting a pretty good chunk of the body away with a hacksaw and die grinder. I went back and cleaned up the sharp edges too. The wiring and res went back in to factory locations. I can fit a 6" dia x 7" long filter under there and you can see it from the old brake duct used to be.

Justin aka pistonsuk,

do you have a few pictures of this setup to show us exactly what you mean?

thank you,

I wish I could take some pictures, my car is 2000mi from me. I will be home from school in May. If anyone still has interest I will post some then.

Here is a really lame diagram.

Your intercooler pipe route is not an option for cars with A/C. Just a heads-up for anyone considering it.

 

that is the headlight washer bottle on some models but most FMIC's need this space also for piping unless you go with a SMIC.

 

The S5 parts fiche shows it as being for the windscreen washers. It's a 5.7L reservior (compared to 1.5L or 2.5L on the right side), which seems a tad excessive just for headlight washers...

 

I'm just finishing up getting my sub zero bottle to work for washer fluid. I switched pumps nad am just sealing it up right now so it doesn't leak.

 

I have AC on my car. I did have to bend the high pressure AC line into a new shape, but this wasn't difficult.

That's very interesting to know. Got any pics?
