N54: Trying to install MMP inlets in E60 535i

I'm trying to install MMP inlets in my 535. The front was not much of a problem but the rear is getting hung up on a bell housing bolt and I cannot get the inlet past it. I've put a couple small gouges in it trying to yank it past. I've even coated it in Vaseline but it will not budge. Any tips on how to get this rear inlet into position? Thanks in advance guys
