Coolant Leaking Somewhere

Hello guys, so I took my G37 to Infiniti for an oil change and they told me that my right side "throttle body hose" is leaking and they have a picture to provide.

I am wondering what exact location is this at? Also which Z1 silicon hose kit would I able to use to replace it.

Picture has been attached for reference.

Thank you!

Can you remove the engine cover and take better pictures of the leak?

This link about cleaning the throttle body has some excellent pictures showing the right/ passenger throttle body (I highlighted the coolant hoses:

​​​​​​I don't think Z1 has the throttle body hose(s) available in silicone- at least they are not listed in their "Master Kit." You can always email them and see what they say.

I tried looking for the leak myself, could not spot it at all.. The dealership was the one who took a picture of it.
