Review on AEM 21 8310DP Polished Intake System by Nick Colton
Terrible Emissions System Upgrade
I purchased this product hoping it would improve the performance of my automotive, but it ended up causing more problems than it solved. Thanks to my knowledge gained in practice, it was obvious that the installation instructions were unclear and the fit of the components was loose at best .The only pro was the polished surface which did nothing to improve the functionality of the system. The cons included decreased gas mileage and increased emissions output, making this upgrade a waste of money and time..
- Improved engine performance and throttle response.
- May require professional installation due to complexity.
