2012 4L 3.0T: any preemptive maintenance to do while supercharge is off?

[50lbsofsalt]

I've pulled the supercharger and upper plenum/intake to facilitate replacing the oil filter housing and the upper timing chain cover gaskets.

Are there any other maintenance items under the supercharger I should replace since I have access? I'm thinking along the lines of any o-rings or hoses that are super easy to access right now.

Thanks!

Since no feedback I'll be buttoning this back up today. Thankfully the supercharger is surprisingly easy to remove in case i need to get back in there later for PCV or other work.
