Advice needed for purchasing a spare intake manifold to fit a 2017 Prius v.

Hi everyone!
I recently purchased a 2017 Prius v with 114k miles on it. I'm planning on servicing the EGR and EGR cooler to try and keep ahead of problems. To save time, I'm thinking of buying a used replacement intake manifold that I can have all cleaned up and ready to go. I've already bought a new Toyota EGR valve and I'm planning on looking for a used EGR cooler that I'll clean up as well. Is there any advice on purchasing a used intake manifold ("EU" 7th and 8th VIN character)? Is a used intake manifold for a 2012 Prius v as good as one used on a 2017? Or, were there improvements made along the way to the intake manifold so I would actually be better off looking for one closer to my 2017? I've also seen new intake manifolds for $85.00, but I think they're after market, which I know nothing about.
Thanks a lot, Thomas
