AEM Cold Air Systems deliver maximum performance gains through all-aluminium, mandrel bent tubing, tuned in both length and diameter and are easy to install without the need for inner wheel arch cutting or modification. The filter element with built-in velocity stack is especially designed to create a massive increase in air flow capacity. Tested by all import performance publications, the AEM Cold Air System substantially out performs all other systems designed for street use. This is by far the most cost effective way to make horsepower. Picture is for illustration purposes only – actual goods may differ in appearance and design.
