Hello I’m new to the forum. Does anybody have a part number for the air cleaner inlet hose?

 

It's called an adapter. GM p/n 22505354

 

thank you for the part number. I see that’s it’s discontinued. Any idea on where I can find one?

 

Try ebay.

If you still have the scoop part in the front, that's good, otherwise you'll be needing that too. GM p/n 1257795. The scoops are sometimes harder to find new than the hose although they do pop up every now and again.
