Gains all around
This AEM looks awesome in my car. It was a tad bit difficult to remove the reasonator as instructed, but other than that, it was a breeze installing this AEM. Filter is not a cheapo. I've noticed some gain in hp(not much) and just in sound alone when I punch it. Sounds meaner. If you're wanting to buy this for massive hp gain, this isn't what you want though.
For the love of driving.
This intake is sweet. I put in on my 05 mazda 6s and immediately, the sound was awesome. Before, it sounded decent, now people ask what kind of exhaust I have, and this intake is the only engine mod so far. AEM advertised 5-7% HP increase, I'd say that's about right. I think there's a bit more grab between 3-4k rpm than there was, and maybe a little more kick at 4.5k, which is usually the peak of the power band. Not sure about gas mileage yet, but I know I just rev if alot??
