Just happened to notice this as I was doing the diode mod yesterday, I'm sure its not the right part as its just a flattened out piece of radiator hose... Any one know what part number I need to look for to replace it? Thanks.

 

Audi B5 A4 Quattro 1.8T > Engine > Emission > ES#9703 Air Pump Hose - 058133785B

Obviously it can be made for cheaper

 

thanks much sir.

 

its just for secondary air injection. you don need to have it but you may get a mil wihout one. i just put a piece of hose on it. the whole sai system is pretty useless bu if you dont want a mile just throw on some hose

 

yah i figured as much, there is a radiator hose on there now. But its all flat and weird looking (cant really tell in the pic) and doesnt look like itll hold up to much (although its been on there for at least a year without me noticing haha...)

 

You can get a plastic elbow and just cut that hose into 2, and add in 2 more clamps and it's fixed. Cost maybe $5 at lows or HD
