I checked the number on the top of the battery... it was an interstate 91 which if i remember correctly was the battery I just got for my roommie for his 1999 323i. It looked about the same at least...
I agree... that was the smallest battery I have ever seen in a diesel. I mean i could pick it up with one hand where the autozone duralast took two hands and some careful placement to not drop it on the car... lol lol...
