B8031A0
Allows you to directly bolt up the 2013-2018 4.0T engine (EA824) to a B8/8.5 4.2L-equipped subframe. 2 spacers fill the gap between the motor mount and the subframe.
-
For B8 cars with hydraulic steering, you do not need to get a different subframe. Any B8 subframe will work.
-
For B8.5 cars with electric steering, you will need a subframe from a B8.5 RS5 (8K0-399-315-H). The reason is that there are missing bolt holes on the B8 A4/S4/A5/S5 subframes needed to mount the V8.
- Only use 3.0T engine mounts.
-
Make sure the subframe you purchase comes with the original engine mount heat shields shown in the photo below; they are needed for the swap. Part numbers underlined below have been verified by us and used in a swap. Others are part numbers we found using Audi parts diagrams; use at your own risk, and please let us know if you confirm they work.

-
Left - 8K0-399-059-B or 8K0-399-377-AE
-
