Audi strikes again...

Bought some spark plugs for the V8. Correct to ETKA, they are the wrong ones. Returned them.

ETKA shows- 101000052AA/HGR7KQC
Audi currently only list the audi part number, but cannot actually confirm the spark plug that corresponds to it on their current systems.

So I shall soldier on. But would someone in the know, confirm?
ABH V8. 1992 engine.

85 WR quattro
90 V8 Silver, 91 V8 Black, 93 V8 Lago
93 100e quattro V6. Titan, i think
