The AEM dry flow was easy to install and fit perfectly! Best of all no oil to mess with! I would highly recommend this filter to anyone who is tired of messing with filters that you hafta oil!

Fits and specs are as described. I did notice a small change in sound from the volant filter. No performance change. I think the description was a little off though as i was expecting the black filter and it is red. No problem though bc the red is what i wanted

Filter looks different from my old AEM filter. Noticed a decent change in throttle response and mpg once I installed. They say these last forever, but I went ahead and bought a new one since mine was looking rugged. 50$ every 40,000 miles isn't bad.
