the euro plate covers the nasty holes the previous owner left me with. he botched the bumper up pretty good.
the hose is the fancy racing stuff that is smooth inside and heavy ribbed outside. it runs up the airbox. since the underhood air intake still functions, i have no worries about injesting water. the lower intake hose just gives the car another shot at fresh air.
i may take the bumper off later this week when i install a n75-j and the samco inlet hose. if i do, i'll take some good pics of the CAI mod.

print out one of the close-up pics and take it to home de' pot with you. those slackers should be able to find it with a pic.[up]

FWIW, the only mesh my HD carried was much heavier gauge and not wide enough to span the center area. i snagged these already cut and painted for about 30 bucks in the classifieds.

personaly i think you should custom fabricate out of aluminum a funnel type peice that would cover up the whole left side of the air dam into that hose you made.. i did this on my old car and was much more effective.. if you dont know what i mean i will explain of make u a picture in photoshop. just think of a funnel... i used a funnel once and it worked just fine.

did u have to remove /relocate some stuff for that tunnel to fit? I looked @ mine and dont have room down there.

i've been thinking about making a funnel/ducting but haven't had time. for the most part, it is sucking air in anyway. even at idle it has a little suction. at full throttle i'm sure it is just hoovering up whatever air molecules it can get to.

the previous owner did the mod. i just got around to taking some pics. it looks like it just fit right through.

just don't go through puddles any deeper than that inlet hose is off the ground. It would no longer be an air inlet, it becomes a straw.

^^ yup, true

yeah..but that inlet just feeds the filter....i dont think its directly 'connected' to the filter... so not gonna have any suction...

alright, i took some more photos. i just laid the camera on the ground and shot upward so it may be a bit difficult to get oriented. look for the big flange that holds the bumper on. that and the location of the diverter valve will help you figure out what is where.

it can't be a straw. that just won't happen. the airbox has two sources of air: the bumper inlet and the inlet between the hood and grill.

water bong physics 101:
put your thumb over the carb hole and you can suck through the path of more resistance; the bowl. remove your thumb and all the air goes in through the path of least resistance; the aforementioned carb hole. the carb hole in this case is the hood inlet. there is no thumb there.

^^^ um... ok [:D] - gotcha. didn't realize that was the second source of air intake

"since the underhood air intake still functions, i have no worries about injesting water. the lower intake hose just gives the car another shot at fresh air."

eh, i don't read thing either. now you know why the dense folk still think your sweet rear brakes will blow your bias.

ha, normally I read everything.. but I guess in this case since it was a black b5 avant, I just skipped to the photos. look'n great.

right back atcha.

what front bumper are you running? it looks great, is more aggressive than stock, is cleaner than RS4 (not diggin the gills), and it lines up better without skirts.

nice set up, i have a very similar set up just finished b4 waterwagens, but it is in different material, i will post some pics later on~

looks good! cut the bars from the center n itll look cleaner [up]

what a great way to break it down, simple for understanding[wrench]

the college kids and the dropouts can both relate to my little metaphor.

6'3". that's about 1/2" too tall to fit comfortably in the car with a helmet on. SA helmets are really bad since they tend to be a touch thicker than DOT. i had to get race seats to keep me in place on the track. my left ear is about even with the seatbelt mechanism and my right knee is almost touching the ignition key.
the height issue is why i just looked at a magnum hemi. what a turd of a car. it'll take more than a decent engine to sell me that bland lump of 70's plastic.

That's the way it should be done if your sporting an RS4 grille.

the front bumper is the kerscher half bumper molded into the oe bumper

your metaphor is flawed. there is no "thumb" when water is getting sucked through the second air path. its true that the path of least resistance will be the primary intake by the hood, but water will still make its way up and into the air box.

how comfortable would you be running this setup on a 3 hour highway roadtrip during heavier rain? i wouldnt be.

your argument has no merit. i have a physics book here if you want to borrow it.

it takes a pretty healthy pressure differential to pull water uphill. the water would then be in the bottom of the airbox. it would then need to be sucked off the bottom and up through the panel filter and through the rest of the system. ain't gonna happen.

it has been this way for more than two years. i did an 11 1/2 hour road trip from michigan to alabama through some nasty weather. it wasn't a problem.

haven't you ever tried drinking through a straw with a tiny little hole in the side? hard to do isn't it? now cut a whole chunk out of the side of the straw and try to get water into your mouth. ain't gonna happen.

thanks for the info audisnapr. i've been looking into that one for a while and thought it looked familiar.

here is my setup, sounds awesome~
But i still need to find a rubber strip to seal the top of both heatshields.
