    More Horsepower and Torque. Are you looking to boost the power and performance of your EcoBoost Mustang? If your answer is a big yes, you should consider installing a Roush Level 1 Performance Pac. By combining their proprietary Flash Pac custom tune and high flow Cold Air Intake together into one convenient kit this Roush Performance Pac will dramatically improve the performance of your turbocharged 2.3L engine. After installing the Level 1 Performance Pac on your EcoBoost Mustang you will see an exceptional increase of over 51 Horsepower and 45 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 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 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.

    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 manual and automatic 2015-2017 EcoBoost Mustangs equipped with the turbocharged 2.3L Inline 4-cylinder engine.

    Hello, I was wonder if you would recommend this product over the Ford Performance Cold Air Intake Kit With Calibration, I'm looking for the most powerful kit, what is your professional opinion?

    • The Ford Performance Power Pack 2 offers Peak Gains of 21 Horsepower and 24 ft/lbs of Torque, and the Roush Power Pac - Level 1 has an Increases of over 51 RWHP and 45 ft/lb RWTQ. If you are looking for more power, I would recommend the Roush kit.

    Does this calibration kit disable the Active Noise Cancellation system like the Ford Performance Power Pack? I'm one of the few that enjoy the enhanced sound.

    • The Roush Power Pac - Level 1 calibration does not disable the active noise cancellation system. It is simply meant to enhance the performance of the Ecoboost Mustang to give it a more "sporty" feel.

    what happens if i install it on my mustang since its not legal here in ca?

    • According to California state law, installation of these parts on a pollution controlled vehicle in California may result in the DMV revoking the vehicle registration and title, refusing the transfer of registration, and/or the vehicle failing smog inspection. Law enforcement may also cite you for the use of an illegal aftermarket part and seize your title and license plate.

    If I wanted to add Turbosmart IWG75 Internal Wastegate - would roush be able to incorporate this still have optional warranty, or is that optional warranty only good for mustangs that have 0 modifications that would in themselves affect tune?

    • In this case, any warranty questions should be left for your dealer to answer as there does seem to be a lot of variance of what does and does not void the warranty.

    My dealer does warranty this product if installed by them but advised me of mpg to drop to around 16 in town and 20 on road and wouldn’t be able to use any regular gas or 87 octane at any time.

    Hi , this says Calibration Optimized for 91 Octane Fuel, Can it be Calibrated for 93 ? Also i`m hearing airaid and C L give the most performance in means of HP and Torque. I just bought a 2017 ecoboost premium and i need a new intake and i dont want to have to buy a second , Ive used Roush before but this seems pretty pricy in comparison to the others. 1 answer

      Insane gains

      My buddy ordered this, and we put it on, and I'm just blown away at how much gain he got for the money. Ecoboost definitely is no joke.
