I ordered and installed this one:
eBay Motors: 95-99 Eclipse Turbo GST GSX/Talon Air Intake Pipe * RAM (item 380008833985 end time Mar-27-08 10:13:15 PDT)
It was a simple install. The only warning is that it pushes the FIPK more towards the fender, but that isn't necessarily bad really.
Also, you might want to consider the "in-line" oil catch cans. You can run a search for it, or just run over to your nearest automotive store [Autozone, Pepboys, etc.] and buy an "inline fuel filter" as they're called. Once again, just install in between the line from your valve cover to intake piping and you can see it catch some of that bypass gunky junky.
Hope that helps in addition to what the others have already said!
