AEM has made this one of the best aftermaehet products you can buy. The instructions are super clear, the appearance is amazing and the performance upgrade will leave you wondering why you did not purchase this earlier. If you want an amazing sounding intake that is easy to install and makes everyone in your toaster do a double take....this is the intake you need to buy!

Part took about two weeks to arrive.Install took about 90 minutes.Directions were precise and had step by step pictues.Fit was perfect,except AEM logo is barely visible with pipe installed properly. Only difficult part of job was that filter has to be slipped through wheelwell then installed from above.Immediately after install there was a noticable improvement in torque.Also engine sound is much more "throaty" especially above 3500 rpms. Since I disconnected battery to do job, my mileage computer reset. My avg. mpg is up to 25 and climbing. I averaged 27mpg prior to the install. I'm hoping to get 29 mpg average with the new intake but the car sounds so good it's hard to keep my foot off the pedal.Overall it was an easy,inexpensive mod with a large impact on performance.

WOW... This is the first CAI I've purchased and I must say that AEM makes the best products for any car. The throttle response, improved mileage, ease of installation, fit, function and sound are incredible. If you're looking for a CAI, AEM has what you need!!!
