This revolutionary breakthrough in inlet system design delivers more horsepower and torque-throughout the entire rpm range-than any other performance air induction system. The AEM V2 Cold Air utilizes a dual chamber (using two different diameters and lengths of piping), to create multiple frequency sound waves that help charge the cylinders with air throughout the entire rpm range. Pending C.A.R.B. exemption (50-state legal). Utilizes a complete hardware kit with soft mounts for a guaranteed perfect fit. Unique, Titanium-look zirconia-based powder coating reduces heat soak and dnhances looks. One-piece, four-ayer, cotton-guze AEM air filter eases installation and features an exclusive air horn design that improves performance.
