Replacing the air filter is a piece of cake. It's 60 seconds once you get access to the engine compartment.
I bought my 03 986 and immediately replaced the filter -- the dealer who sold it to me didn't bother, and I found the filter to be in pretty bad shape. Dirt and oil on it. No MAF issues though.
Re: K&N impact on HP, a new filter is not an elixir for suddenly adding tons of noticeable HP. Think about it -- would the engineers who design that car really sacrifice HP because of, what, a religious devotion to paper filters? No way. More HP on a sports car directly translates into sales, and no company is going to say "Yeah, we could put that cotton filter in the car and boost HP by 10, but because we just love paper filters, we won't." I'm sure I'll trigger a bunch of posts from some K&N salesman or distributor by posting this, but the notion that you're going to get some huge increase in HP or MPG because of an air filter is fantasy.
