both items are for US Spec engines, I have no doubt the engine would run on either metering unit but you would need to dyno it to check the air / fuel ratio across the complete rev range.

However here is the throttle body you need...

And the airflow meter is here.

... Some other things to consider..

Get a Volvo 240 metering head and air flap.

Audi throttle body

Ported intake.

These are also restriction points when working with Kjet.

hi preen,

which audi throttle body do you recommend and would you port the standard intake or is there a link to an aftermarket option?

i currently have a 76 mk1 project and looking to keep the original engine just fix it up and maximise its output to a safe easy daily drive level.

thanks,
cam

some type of larger exhaust, a modified / better breathing camshaft, upgrade the throttle 192.168.100.1 192.168.1.1 body as preeny has said along with some de restricting of the inlet will give you some more power
