I recently had my bumper cover and my chin spoiler replaced on my 2000 Type R. I double checked and triple checked the part numbers. The bumper cover had to be special ordered and the chin spoiler had to be special ordered also from Acura.

Now, here is the problem, everything was mounted up the same exact way. But for some reason the the chin spoiler is a lot more recessed than before. I still have the original parts. A former Acura Tech. told me that Acura changed manufacturers of their bumper covers and chin spoilers and that accounts for the minor change. After looking at other Type R pics I noticed that some look the same as mine(now, with a little more recessed chin) then I also notice that some look like mine did originally also(with the slightly more protruding chin).

Is there a part # difference

 

I dont think I know what you mean, please post some pics if you can. Like one that looks like yours and another that looks "normal"
