Description
AEM Dryflow Air Filters were developed in collaboration with K&N, the inventor of High Flow Air Filters. We adopted some of the best elements of cotton air filters into a new generation synthetic Dryflow Air filter. The three-dimensional filtering medium uses both depth loading and structural screen wire to enhance airflow capabilities and make the filter incredibly easy to clean. The result is a true performance air filter that does not require oiling, carries a lifetime limited warranty and is capable of increasing horsepower and torque.

AEM Dryflow best bang for your buck!!!
By AL-G on 10/19/2013
After 8 months of using the original filter that came with my eBay cold air intake I decided to replace it with this AEM filter. This filter is a lot bigger, and looks more aggressive, I was worried it wouldn't fit, but all u have to do is tightened the clamp to where it's a tight fit to ur CAI tube. I converted my CAI to a short ram due to Raining season coming soon to my town, like I said looks very mean/aggressive. Stands out a lot in my engine bay. Sounds good too. 2004 Civic/ES1. IMPORT KAOZ all day!!!

This is a replacement filter for an already existing system. Needed to replace old filter that is a few years old. Perfect fit, fast delivery, great product!
