I have a 2017 3.5L V6. I'm about to attempt changing the spark plugs. What are the gaskets I need for the lower manifold (I think ? ).

Are they 6 separate gaskets for this engine? What's the proper name for these gaskets? Do you know the P/N for Advance Auto or Autozone?

Looks like I need to remove the upper intake manifold to get to the passenger side plugs

I'm looking for videos on this engine but not finding them. Can you suggest a good video to watch?
