None that I know of...it's basically the same 3.0L 6G72 engine. The electronics change, like the ECU and ignition, but the mechanical parts are almost identical.

I've checked several water tubes online, and they don't seem any different regarding size and the angle of the two outlets on the rear.

I found one used for $25 which is pretty good, and one new for $53. I'm probably going for the new one, just to make sure that I NEVER have to replace this again.
