You might get a very slight horsepower boost. I have run K & N stuff in a couple of my new Ford F-150's and there was NO improvement in fuel mileage and my butt dyno detected no power increase. The stock Honda intake does not seem to be too restrictive and has a good cold air inlet that is up high to prevent water from coming into the intake. A K&N filter and cold air intake (CAI) would be in the open and I think get very dirty very quickly. Also the CAI would be where there is lots of heat coming from the engine versus the stock setup. If you want a horsepower boost run premium fuel. If you want fuel economy drive with a lite foot and keep tires at recommened or above pressure.
