Review on AEM I.A.S. Chrome Nissan Altima 3.5L V6 07-11 by Nathan Guzman

I installed this AEM 21-499P air intake system on my 2009 Nissan Altima 3.5SL. Over the past 400 miles I've noticed a significant improvement in "get up and go" along with a sense of increased power. Before the install I got 30-31.8 mpg highway and 26-26.8 mpg city. There was no improvement in fuel economy, but that may be due to not being able to keep my foot off the gas. In terms of cost, this was NOT a great investment for me, although the price was lower than anything else in the same category.
