Take your Mustang’s performance from mild to wild with the new ROUSH Level 2 Performance Pac. Increase performance by 24 rear-wheel HP and 18 ft-lb rear-wheel torque with a few simple upgrades. Countless hours of engineering and testing went into designing the ROUSH Calibration, Cold Air Intake Kit, and ROUSH Axle-Back Exhaust System in this Performance Pac for a thrilling driving experience.

The Cold Air Intake Kit has been redesigned and engineered specifically for the 2018-2120 Mustang 5.0L V8. Replace your restrictive factory air intake system with our Cold Air Intake Kit for improved throttle response and a sportier driving experience. Our new specially designed "see-through" lens on top of the air box displays the air filter as if it were an open airbox. The enclosed airbox creates more horsepower by keeping inlet air temperatures down.

Our Axle-Back Exhaust System has that signature race-inspired rumble you crave. The 2018-2120 ROUSH Performance Axle-Back Exhaust System is constructed of corrosion-resistant T-304 stainless steel, and is mandrel-bent for high-performing airflow. Thanks to hours of research and development, testing, and validation, this system improves flow and reduces back pressure.

The Performance Pac kit includes the air filter with clamp, injection-molded lower airbox/tray with installed foam hood seal, clean air tube, and all required mounting hardware. The kit utilizes all factory emissions and vacuum lines. Factory mounting locations and hardware are utilized to allow for quick and easy installation.
