Hi

I am doing a swap from a k8 to a KLDE with the ZE curved neck manifold. During part switching between the engines I came over this odd sort of vent or coupling from the ZE manifold.






As you can see, It's not on my k8 manifold.




Does anyone know what this is and more importanly what I should do about it?
I hope to get some answers cause I haven't bin able to find it by searching..

Nothing.. mine not even plugged im boosted and doing good.

That hole doesn't go into the manifold..it geos back out of it. you see that plate with 2 screws on it. It goes to there.Its something to do with egr. Leav ita lone you should be fine.
