This is a new original Ate vacuum brake booster.

Ate is the Original Equipment Manufacturer (OEM) to Audi for this part.

The Audi part number on this is 443-612-107-A.

I am not sure if this is available from Ate or Audi any longer.

The last recorded retail price I show was $645.00.

This genuine new Ate brake booster will fit the following models:

5000 - 1978, 1979, 1980, 1981, 1982, 1983

5000 - Without hydraulic brake booster - 1984, 1985, 1986, 1987, 1988

5000 Turbo - 1980, 1981, 1982, 1983

All applications are accurate to the best of my knowledge, however I advise double checking with your dealer for application to your vehicle, or email me with your VIN # for clarification. I can not be responsible for inaccurate or missing application data, however I will take an item back if the error is mine.
