Actually, dyno result _can_ show good hp gains. Look at the NPM article of the NISMO intake they tested on the Altima SE-R, something like 28-peak hp. BUT, if you read the article, they did those numbers with a cool engine. Once it comes up to operating temperatures, they claim "heat soak" and only get 1hp/7.5tq increase per their dyno chart. So, for everyday travel in the vehicle you are pretty much getting a slight tq increase and more sound. That's about it for your $300-400 bux.
Of course, an intake with exhaust would give a better chance for usable gains.
