Review on AEM 21-499C: Elevate Performance with Cold Air Intake System by Josh Goldsmith

Finally decided and bought this inlet. I am not disappointed and have received many compliments and smiles from the people who have ridden in my car. Sounds like a G35 at low revs. From around 4000 rpm it has a very deep rumble under the throttle. However, it's quiet when you want it. Installation was easy, taking about 1.5 hours with just one person and basic hand tools. The only complaint I have is that the heat shield rubbed against the brake fluid reservoir when first installed. However, once the heat shield was flexed, it stopped rubbing against it. Otherwise the fit and finish were excellent. Seems to be very well put together. I don't feel any performance gain and didn't notice the MPG gain.
