Expensive, but worthwhile
This is my first full AEM intake system, I’ve had a K&N intake on a previous car and this system is comparable. I enjoy the fact that the AEM provides dyno results to show that the system actually makes HP and torque, and exactly where it does. The instructions leave something to desired, but if I can figure it out, almost anyone can. The install took me about an hour and I’m not very mechanically inclined. I do have a small complaint about one of the bungs not screwing in cleanly (I tried multiple times), but it hasn’t seemed to cause any actual issue with the performance of the system. In terms of noise, expect it to be fairly loud under load, especially if coupled with an aftermarket exhaust. The butt dyno says that it’s given some power and responsiveness. Not the least expensive system, but I’m happy with my purchase.

It does have a noise but its great product.
It does have sound like exhaust but its a great product and it will help you vehicle very much i have got much better throttle response with this intake i will give it 10 out of 10 but about the price i am giving it 6 out of 10 its a little pricey but over all its a great product.

Solid intake system
Intake was easy to install with clear instructions. My 2019 i4 Camry SE sounds so much better on acceleration. Gives it a nice growl as the air is drawn in and masks some of the direct injection noise when that’s active. All CAI makers show dyno charts with increased HP. I’m sure a bit of additional air drawn in surely helps; but any noticeable difference on throttle is not felt as most HP is added on the top end. It’s pretty rare I’m reaching 5000rpms in daily driving. I don’t really pay attention to MPG as I live close to work and fill up once a month so not sure if that’s increased or decreased. No aftermarket tuning done either. Car is stock less this addition. Solid investment just for the sound improvement alone though.
