I just got this Outback so its almost all stock.

I bought this intake on eBay.

I bought it for another make so I was left with extra parts due to the limited space under the hood.

I had a hard time installing it. I had to drill two extra holes and put plumbing pipe fittings with the threads to connect the other two hoses.

For the air flow sensor I went to Pep Boys and got the necessary hardware. I still had to do some customizing tho.
