Checking Maintenance Items - 2013 Prius Plug-In

Hi all,

I have recently inherited my family's 2013 Prius Plug-In with 125k miles. I understand that these Gen 3 Priuses have head gasket issues if some maintenance items are not taken care of. That being said, I'm not scared of turning a few wrenches and want to do everything I can to keep this car in tip-top condition under my ownership.

Next week, I plan on doing an EGR overhaul, including cleaning the intake manifold, cooler, valve, pipe, and changing out spark plugs and ignition coil packs because I doubt those have been touched in who-knows-how-long. Below is a list of P/Ns I have compiled from RockAuto and that I plan on ordering in order to do the job:

4x NGK 93501 - spark plugs
4x WALKER PRODUCTS 9212126 - ignition coils
1x MAHLE / CLEVITE MS19723 - engine to intake manifold gasket
1x MAHLE / CLEVITE G32731 - gasket from intake manifold to tube
1x MAHLE / CLEVITE G32732 - gasket from tube to EGR valve
1x FEL-PRO 72636 - gasket from EGR valve to EGR cooler
1x FEL-PRO 72565 - gasket from EGR cooler to exhaust manifold

Did I cover all the bases for the job? Are there any other recommendations in terms of maintenance, given the mileage? Thank you so much!
