Y to the accordian hose? Audi lists an alternate for our engine(guessing A box hose) but not sure if it has the quick connect fitting like the newer manifolds have('01.5). It is a direct connect between the brake booster and intake manifold w/o the extra line...

Default It likely does not. On the older manifolds it is a slide on connection as...

Hence, the ease of using the Allroad manifold instead of the 02 S4 mani. with the clip on connections. Just a solid hose. That's also why AWE plugs the hole in the accordian/silicon hose. Cuz us older Sfizzours don't have that! :-)

Default Lol, thx Gary. I found a direct hose that I may try - supposed to have a quick connect

fitting on the mani side... that is if it doesn't cost too much. My M has the two Y connectors(brake booster, mani, and accordian) and I was looking for a sano way to remove the extra leg vs the plug route with the boost/vac fluctuations and all.

Default Quick version...lets see if I can do this right...

Remove Y-pipe...remove fuel rail...remove old manifold...Cut off old spider piping from top pass side. Shown in pic...save black air release valve.
<img src="http://pictureposter.audiworld.com/42872/picture_029.jpg">
Remove green air release/check valve on pass side. Buy new hose...uh, part # coming write up (buy 2 for cleaner install, and you'll see later)Actually you can see the part # in the pic...but I'll post it in the write up.
<img src="http://pictureposter.audiworld.com/42872/picture_039.jpg">
New hose to go to manifold...taking place of F-hose on older cars (also used in rear of mani.)
<img src="http://pictureposter.audiworld.com/42872/picture_041.jpg">
Put manifold in with some other little quirks that will be in the write up. Use 1/2" fuel line from top passenger side of spider assy. valve to the air check valve removed from F-hose under old mani. Use black plastic 1/2" male to male connector into valve. Out of valve use 2nd hose ordered from before. Reason for this..this hose flares down from 1/2" size needed out of valve to 1/4" size nipple on manifold as shown in photo. I'm still waiting for my second hose from dealer. In the meantime used a ghetto rig...
<img src="http://pictureposter.audiworld.com/42872/picture_042.jpg">
Ghetto rig(brass fittings, 1/2 "male to 1/4" male downsizing the fuel line. Stock hose does this so two less fittings and less chance of leak.)

The quick write up..put everything back in, in reverse order. FPR goes in same way...uh the EGT sensor plugs also have to be mounted differently...but very easy overall. Whew!!!
