What are things I can add to my 2007 Ford Mustang?

Well, I just bought it and was looking around like cold air intakes, etc... Can't find one that fits in it, I've actually noticed lots of the things I was looking at that go for the 2002 mustang I was planning to buy don't go on the 2007 (I know there's a limit like 2000-2004 etc. Just can't find the right part for the '07)

So what are a few things I can add to this car?

Edit : It's base model and all stock.
