Review on 🔧 Gun Metal Cold Air Intake System by AEM Automotive (AEM 21-483C) by Seth Singh

Just finished the installation and just got back from a quick test drive. If you drive carefully, you won't notice it at all. I find that my engine now sounds like it should. Once installed, my engine started and started almost immediately; significantly faster than with the standard air box. I also feel a quicker throttle response and overall the car runs smoother. Installation took just over 2 hours (I took my time) and was pretty easy. The instructions that came with the CAI were easy to understand. Attention: To install this and possibly all other CAIs for this vehicle, you must remove the front wheel on the driver's side. This can be a problem for some. My car is a 2007 Mazda6s with a 3.0 V6 and I had no check engine light. I plan to come back in a few months and update this review with win or loss in mpg.
