Completely agree that it will not be worth your time and money, and I have done a lot of research into this, but if you are just talking about the K&N air filter, not CAI, that's something I would do. I put these into my car and TV. They do give just enough extra performance that you can barely notice if you drive it every day, they're cheap, and pay for themselves in reuse.
