I do know that we have the Alpina B10 engine in the 4,6is. But I checked another 4,6is today and he did not have the Alpina badge on his engine. Am I special..... ??
The badge is inside the engine cover, and on the back of the cover its says ''Genuine Alpina Part'' on a yellow sticker.
(yeah, I know, my enginebay is dirty.....)
