    More Horsepower and Torque. Roush has found that the turbocharged 2.3L engine of the 2015-2017 EcoBoost Mustang takes very well to performance modifications and it's exactly for this reason why they developed the Level 2 Performance Pac. Roush has combined their proprietary Flash Pack custom tune, high flow Cold Air Intake and free flowing Axle-Back Exhaust together into one convenient Performance Pac to dramatically improve the output of your turbocharged 2.3L engine. After installing the Level 2 Performance Pac on your EcoBoost Mustang you will see an exceptional increase of over 60 Horsepower and 51 ft/lbs of Torque at the rear wheels.

    Roush Calibration. Roush engineers developed their dedicated premium fuel calibrations under laboratory conditions to increase the horsepower and torque of your EcoBoost Mustang across the entire RPM range with their Cold Air Intake and Exhaust installed. The improved boost and throttle mapping of the included Roush tune will also give your turbocharged Mustang a much sportier feel. Roush's calibrations have been optimized for 91 octane fuel, they are compatible with lower octane ratings with reduced power and performance output.

    J2534 Interface Tool Required. Just about any dealer can perform this calibration upgrade in under an hour without even breaking a sweat. The Roush Flash Pack Calibration is flashed on to your Mustang's ECU using Roush's RDT software and an industry standard J2534 interface tool. Please note that a dealer service charge may apply.

    Cold Air Intake. Roush's EcoBoost Cold Air Intake was engineered using CAD data to eliminate restrictions and to optimize air flow. Injection molded from premium automotive-grade materials, this Cold Air Intake will last a lifetime. The included high-flow dry air filter provides excellent filtration of harmful power robbing particulates. The filter is composed of two layers of wire mesh for durability and is proven to retain its shape even under high airflow. Washable, this dry air filter does not require oiling, saving you time and money.

    Straight Forward Installation. The Roush Performance Cold Air Intake Kit is designed to install easily with just basic hand tools. No extra modifications or special tools are required for proper installation. All necessary parts and instructions are included.

    Axle-Back Exhaust. Boost the sound of your turbocharged 2.3L engine with a Roush Axle-Back Exhaust. This innovative Roush exhaust system features a pair of hollow chambered mufflers that results in increased air flow and a unique sound, with no in-cabin "boom" normally found with performance exhaust at cruising speeds. Constructed from mandrel bent 304 stainless steel piping for strength and enduring corrosion resistance, this Axle-Back features two stainless steel 4" tips. The 4" tips are finished with a new chrome flashing process that is resistant to discoloration due to exhaust heat.

    Cut & Clamp Installation. Installation of the included Roush Axle-Back Exhaust requires cutting and removing the factory muffler assemblies and clamping the new muffler assemblies in their place. Clamps, hardware and installation instructions are provided.

    Optional Warranty. An optional 3 Year/36,000 Mile Limited Powertrain Warranty is available through Roush. The optional warranty must be purchased within 30 days of the service installation date. Click here to see more details.

    Application. This Roush Level 2 Performance Pack is specifically designed for use on manual and automatic 2015-2017 EcoBoost Mustangs equipped with the turbocharged 2.3L Inline 4-cylinder engine.
