Review on AEM 21 488B Blue Intake System by Mark Saric
Forget performance, it's all about MPG gain.
Although I no longer own my 2008 Mazda 3 (swapped for a Mazdaspeed) this AEM CAI was amazing. It was very easy to install, gave a decent performance boost and gave me more mpg than I could ask for. In my opinion, the air intake should first be installed in almost every car, because the advantages are obvious. You get a little more power and more mpg, which pays for itself in about a year. All in all, I highly recommend this product.
- Easy to read control panel
- No automatic transmission
