Happy Halloween!

Did a quick smoke test today before pulling the CIS to tackle the Triangle of Death. Found two leaks:

Intake air guide box (930 110 358 05) – the connection point is tearing. Planning to order a replacement - would you go OEM Porsche or aftermarket? The price gap is pretty big.

Pretty sure the second leak is the EGR valve - smoke’s coming out of it. Can I just plug the red and white vacuum lines going to it?
