The Roush Level 2 Performance Pac for the 2015-2017 Mustang GT (421997) adds an exceptional 29 RWHP and 36 lb-ft. of torque to your stock Coyote 5.0L V8. For increased performance without excessive work, this is the kit for you. Additional perks include a sportier feeling and sounding vehicle. These modifications are easy to make, and the benefits behind the wheel are obvious.
Features and Benefits:
- Increased engine performance of 29 RWHP and 36 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

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, premium 2.5” axle-back exhaust, 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.
