Review on Enhance Performance with AEM 21-426R Red Cold Air Intake System Upgrade by Jesse Costello
Major Disappointment
This product failed to meet my expectations. Automotive enthusiasts, do not waste your money. After trying this product, my vehicle had significantly worse gas mileage and no noticeable increase in horsepower. On a positive note, the installation process was relatively easy.
- Easy installation
- Decreased gas mileage, no noticeable performance improvement.
