Review on AEM 21 422C Metal Intake System by Richard Nordstrom

I recently upgraded my car's emission system with a metal intake system. As a result of using this product, I found that my car's throttle response and acceleration have improved significantly. It also enhances the overall sound of my car, making it sound more aggressive. The only downside is that it can be a bit tricky to install, but with the right tools and instructions, it can be done. Overall, this is a great addition to any performance car looking to boost its power and sound.
