Anyone know, or can easy measure, the hose thickness that connects the intercooler to the plastic intake pipe on the cold side? I'm moving my WMI nozzle further down stream, but need to know the hose wall thickness.

The part I'm talking about is the short hose #1 on this diagram:

Here's the hose... I'm thinking 6mm...
