Do you want to take your Mustang’s performance to the next level? The Level 1 Performance Pac is the perfect upgrade to increase horsepower and torque without breaking the bank. Our Level 1 Performance Pac includes the specially tuned ROUSH Calibration and Cold Air Intake Kit, designed to unleash an additional 24 rear-wheel HP and 18 lb-ft rear wheel torque over the stock performance for a thrilling driving experience.

The Cold Air Intake Kit has been redesigned and engineered specifically for the 2018-2019 Mustang 5.0L V8 engine. 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.

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.
