Description

The Roush Level 2 Performance Pac is engineered to enhance the performance of 2015-2017 Ford Mustangs equipped with the 3.7L V6 engine. This comprehensive kit combines a Roush Cold Air Intake, an Axle-Back Exhaust system, and the RDT Flash Software Voucher to deliver significant improvements in horsepower and torque across the entire RPM range. It features a high-flow dry air filter that requires no oiling and offers excellent filtration. The Axle-Back Exhaust system utilizes a hollow chambered muffler design for improved airflow and a sporty tone without in-cabin drone. It is constructed from mandrel-bent 2.50-inch diameter 304 stainless steel piping with 4-inch stainless steel tips. Calibration for this package is optimized for 91 octane fuel, with compatibility for lower octane ratings resulting in reduced power output. The included Roush tune features improved throttle mapping for a more aggressive feel. Flashing the calibration requires an industry-standard J2534 interface tool, and a dealer service charge may apply. An optional 3-year/36,000-mile limited powertrain warranty is available through Roush, provided it is purchased within 30 days of the service installation date. Installation is described as simple, with an approximate time of 2 hours, requiring basic hand tools.
