It will work for you, but you might want to change it at some point. This one is electrically heated, so there is a wire from it what will need to be connected.

Any idea? The port that is at the upper left of the intake hole on the IAD is the vac advance. On the 72 IAD only there is another port down low near the big air opening. There should also be a larger port on the left side, between the #3 & 4 air runners, either above or below, depending on the year. This larger port goes to the pressure sensor. If you've got a 72 IAD with a FI system from a different year, just leave the vac retard port plugged up. > Would it be alright if I hooked up the oil breather to the port that is > for the charcoal canister since I don't have a charcoal canister to begin > with, it fits, and it is on the bottom part, i.e. it will be filtered > through the oil as it should? Yes, but this would make this hose really long and in the way. You'd be better off getting the right air cleaner, and I think these would be rather easy to find. I have several if you can't find one closer. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
