The ROUSH Performance Level 1 Performance Pac for the 2015-2017 Mustang 3.7L Ti-VCT engine adds over 12 RWHP and 13 lb-ft of torque to the stock Mustang V6 Fastback. An optional 3-year/36,000-mile limited powertrain warranty gives you confidence to crank up the power.


Horsepower and torque improvements shown are typical. Individual results may vary.

The included ROUSH cold air kit is fully tested and calibration certified to work seemlessly with our performance ECU reflash and adds a sporty sound to the 3.7L Ti-VCT engine. Our cold air kits are the best in the industry, designed and tooled in CAD to maximize available underhood space, and injection molded from premium automotive-grade materials for long life. With a lower intake restriction over stock, you will never need to upgrade your intake no matter what mods you plan in the future.

Roush calibration engineers have extensive OEM calibration experience and sweat the details to ensure strong performance without sacrificing driveability. Hundreds of hours spent in the lab and on the dyno, testing and validating our calibrations, set our Performance Pacs apart from guesswork tuning.

In addition to improved horsepower and torque, more aggressive throttle mapping and camshaft tuning lends a sporty feel right off idle to redline providing incredible driveability gains throughout the entire power band.

Roush Performance Pac calibrations are programmed easily into the factory ECU via industry standard J2534 reflash interfaces, with our free Roush Diagnostic Tool, (RDT), utility.
