ROUSH Cold Intake for 2011-2014 Mustang 3.7L V6

Cold air intake is a much more efficient method of air intake into the engine than the conventional process of filtering air in a factory engine. The air first passes through a "dam" which insulates the intake air from the high temperatures radiating from the engine. Cooler air enters the mixture, which increases combustion efficiency, throttle response and overall engine performance.
