I can't remeber where this was originally posted ("guess this Part"?), but the turkey made me take a shortcut.

This was the orignal part discussed.....

Was discussed that this might have been a domestic part rettofitted to a spare air cleaner ('72) housing I have.

Still don't know what it does & isn't listed in PET, but see the following......

Now, this is my original (also a 72) & I still don't know what it does.

You can see in the pic that is missing a "leg" - could've happened anytime over the last 30 years, but it it completely different. PN (VW) 022129640 - what's it's purpose?

Also included in the pics is the scewdown bolt for my '72 - soldered wingnut variety.

Sorry - I know this is crossposted, but the Thanksgiving turkey (wild) left me with enough triptophan that I'm getting verry sleepy & don't give a sh_t.

My 72 has the same piece on the air cleaner. so i dont think it was only that one mine is a CA car and it had it. with the AC on the top and everything.

im under the assumption it is a temperature controlled vaccum valve. mine has the two ports and one side goes to the intake manifold and the other side goes to the Vaccum operated valve that opens and closes between pulling in air from the top air horn and the bottom one that is ducted under the motor.

thats my take..maybe its just mine.. but hope it helps..

#5 on the diagram is my AC branded valve
