Review on 🔴 AEM 21-203DK Universal DryFlow Clamp-On Air Filter: Round Tapered; 3 in (76 mm) Flange - High Performance Red Filter for Improved Airflow by Robert Prix

A few years ago I installed an AEM cold air intake on my 2008 Nissan Altima 3.5 SL. This was also a dryflow filter (albeit grey). Since you have to wait until it's completely dry before using it again after cleaning (with good reason, of course), this made the cleaning process a bit cumbersome. So I wanted to grab another filter to use while I clean the other one. I was a bit skeptical because the AEM Dryflow filter that came with the air intake was gray and this one seemed red (not sure if it would be a suitable replacement). However, the pipe was 3 inches, so I decided to give it a try. I'm happy to say that this really is the perfect replacement for what I'm currently taking. Installation was easy, of course, and throttle response is noticeable. Definitely use it as your main filter and my old one as a "backup" if you delete that one. Highly recommended - you can't go wrong here.
