Newbie PCV question

[Cbennett4]

I am wanting to replace my PCV valve. I found where it was thanks to the threads but am curious about the part I got. I got a pcv from Napa:

It does not look like the O.E. one I have in there though. What is the horseshoe pipe for?

Any other tips for removal is also welcome, Thanks!
