🔥 AEM Cold Air Intake System 21-821DS - Boost Performance and Efficiency with 1 Pack Review

Firstly, the power is noticeable, but the intake noise is imperceptible if you have a non-original exhaust. It's still worth it and I'll enjoy the car more now. So for the bad, installation is a pain. The L-shaped adapters are plastic and one of them broke during installation. The metal cover barely fits the entire surface. Once you receive it, everything is fine and fits well, but it is troublesome to adjust.

I received the kit and tried to install, took the stem out and when I opened the kit I found the kit now has hardware, the clips were missing, was one of the foam grommets was missing and the bends for the ventilation hoses were also missing. Tried to contact AEM but no response, or at least not yet. Never mind cause I'm returning it, I spent a hot dime on this kit, at least it can be complete. Next time I'll look elsewhere. Don't neglect the seller, just disappointed in AEM.

After trying to assemble it as it says in the box I gave up after 30 minutes trying to get the whole assembly under the hood once clean . I figured out what they were trying to achieve and just put in the bottom of the airboxes first, the maf pipe to the TB, then the filters and finally the top of the airboxes. everything went smoothly and only took about 30 minutes. So, great product, looks great, sounds great, 10hp dynos. For my dyno run, just don't follow their directions to the end!
