I just wanted to post up for anyone researching that the Perrin Turbo Inlet was a poor fitment on my 05 LGT.
I replaced it thinking I had a tear, but the leak turned out to be the IM Gaskets. I replaced the inlet anyway while I had it out, but the Perrin was nearly 2" too long. It didn't line up with the BPV tubing at all and so I had to modify and cut nearly 2" off of the Turbo side to help it line up with the BPV tube. This, in turn, forced a tighter fit of the vac lines.
It may not be like this for everyone but I just wanted to throw it out there.
Of course, such is the risk with any aftermarket part
