Description
More Horsepower and Torque. The 2018-2020 GT Mustang arrives at your dealers showroom setup for the driving needs of the masses, not for you the individual driver. It is for this reason that Roush developed their Level 1 Performance Pac. By combining their Cold Air Intake and Flash Pack custom tune you will see an increase of over 25 Horsepower and 30 ft/lbs of Torque.
Roush Calibration. Roush engineers developed their dedicated premium fuel calibrations under laboratory conditions to increase the horsepower and torque of your GT across the entire RPM range with their Cold Air Intake installed. The improved throttle mapping of the included Roush tune will also give your Coyote powered Mustang a much more aggressive feel. Roush's calibrations have been optimized for 91 octane fuel, they are compatible with lower octane ratings with reduced power and performance output.
Cold Air Intake. Roush's 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. Please note, if you would like to retain the factory engine cover on your vehicle, trimming to the cover is required.
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.
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 1 Performance Pac is specifically designed for use on 2018-2020 GT Mustangs equipped with the 5.0L Coyote V8 engine.
