After installing a K&N Cold Air Intake, I want to replace it with GM, what parts do I need to do this?

Good call, you will need to install the air filter housing and intake tube. Below is a picture of what you need to do the changeover, I would call an auto wrecker to see if you can get the parts. Check out the diagrams (below). Please let us know if you need anything else to get the problem fixed.

Hi! Thank you for this. I appreciate it. Do you know where online I can find everything/every part and piece needed that’s in the diagram that you attached in your message to me? Thank you.

I would try Ebay, they have everything. Check this out:
