AEM 21 425R Cold Intake System Review

After I put it to the test, I was disappointed with the minimal increase in horsepower and the annoyingly loud sound it produced..

Using this system, our team found that our performance car's emission system improved drastically. It was more responsive during acceleration and there was an increase in horsepower. The installation was easy, taking only a few HOURS. The downside is that it is a bit on the pricey side but it is definitely worth the investment for the improved performance. .

Package arrived on time as usual. This was the first install for me and my son, the whole process took maybe half an hour, plus or minus five. My son notices a difference in sound and performance compared to the machine. I highly recommend this intake system.
