The Roush Level 1 Performance Pac for the 2015-2017 Mustang GT (421996) adds an exceptional 25 RWHP and 30 lb-ft. of torque to your stock Coyote 5.0L V8. For improved performance without much work, this is an easy to install kit with benefits that far outweigh the effort.
Features and Benefits:
- Increased engine performance of 25 RWHP and 30 ft-lb RWTQ over stock!
- Package includes a “Flash Voucher Card” containing the voucher code & voucher family necessary to recalibrate vehicle
- Cold Air Intake is CAD designed for optimized hood sealing to keep out heat and gain maximum performance
- Includes a high flow, high capacity, washable and reusable performance air filter (does NOT require oiling)
- Increased torque and horsepower across the entire RPM range
- Improved throttle mapping lends a more “aggressive” feel to the 5.0L Coyote engine
- Calibration optimized and designed by ROUSH engineers under laboratory conditions
- Can be added to a 2015-2017 5.0L GT Mustang with the ROUSH Axle-Back Exhaust already equipped to get “Level 2” Performance Pac equivalent power increases (29 RWHP/36 RWTQ)
- Includes all necessary hardware
- Made in the USA!
In addition to improved horsepower and torque, our kit also provides improved boost and throttle mapping that will lend a “sportier” feel right off idle to provide amazing drivability improvements all through the power band. Between the revised cold air kit and remapped ECU calibration, Roush takes the guesswork out of performance. These easy enhancements result in serious gains!
Tech Tip: The Roush calibration in our Performance Pac is easily programmed into the ECU of the vehicle via an industry standard J2534 Dongle tool (NOT Included) & our free Roush Diagnostic Tool (RDT) software (note: dealer service charges may apply). Most Roush Performance authorized dealers, should they be equipped with the proper tool, can complete the calibration process in under an hour.
- Powertrain calibration is developed and supported for U.S. and Canadian vehicles ONLY.
- Premium fuel, 91 octane or higher, is required.
- Performance Pac calibration is NOT designed to be compatible with other aftermarket powertrain components.
This Kit Includes:
- Cold air intake kit with re-usable premium air filter
- Flash voucher card with voucher code and voucher family

Attention: Flash card voucher is final sale and is NOT returnable.
