the new AEM in my opinion is better, but only by a little. the gains would be a very low percentage. I dont think the gains is enough to be noticable unless the engine is heavily modded. for example, 1.5% gains on 125 hp car wouldnt be as noticable as on a 200 hp car. I mainly think its just a coolness factor. jux to say that u have the newest AEM intake that is ranked as the best, even if its only better by like 1 hp, its still the best.
