Unleash the hidden power in your 2011-2014 3.7L V6 Mustang with this top-quality Roush Performance Cold Air Intake Kit!
Cold air induction proves to be a more efficient air intake method compared to the factory air filtering process. Consequently, it unlocks unrealized power and enhances fuel efficiency that would otherwise be constrained by the stock air intake unit. Roush Performance cold air intakes bring three key improvements: an upgraded air dam, high-flow air filter media, and a cold air induction tube.
The first step in the air induction process is the air dam. Upgraded air dams effectively insulate against hot air from the engine compartment. The result is cooler, denser air entering the filter, providing a more potent air charge. The second step involves the air filter media. Roush Performance meticulously selects the media to ensure improved airflow while still effectively filtering out dirt from the engine. Once the air passes through the filter, it goes through the induction tube. Each of Roush's Mustang cold air intake kits features induction tubes designed to optimize airflow while maintaining insulation against hot engine bay air.
This kit includes a new induction tube, a complete airbox assembly, a premium synthetic washable/reusable filter (pre-oiled), and all the necessary hardware and instructions for a hassle-free installation.
Rest assured, this kit is backed by the Roush 90-Day Limited Parts Only Warranty, guaranteeing your peace of mind.
