What year did the grill change on the 3 series BMW?
It's all one piece with the hood now.

There have been changes with every new generation. The first 3 Series was the E21, followed by the E30, the E36 and finally the E46 in 1999. Generally, the grills are interchangeable within a family. There may be some exceptions to this rule, though. I don't know my parts well enough to say for sure.

E46 changed to have it connected, probably so it has smoother lines (1999)

I'm pretty sure E36 didn't have it connected

you're right. E36 didnt have it connected.
