Roush Performance has announced the launch of a new performance Pac for the 2018 through 2020 2.3-liter Mustang. The Roush Performance Pac Level 1 is available now and promises to add 33 horsepower and 37 pound-feet of torque over the stock numbers. The Roush Performance Pac Level 1 features a cold air intake that takes cooler, denser air into the engine to increase overall power and boost the sound produced by the Mustang.
The cold air intake includes a high flow, high-capacity washable, and reusable performance dry element air filter that never requires oiling. The Level 1 Performance Pac includes a performance calibration that is optimized for 93 octane fuel but is compatible with 91 octane fuel as well. Roush also notes that the tuning included with the Performance Pac improves throttle mapping to give the 2.3-liter EcoBoost in-line four-cylinder engine a sportier feel.
The cold air intake included in the Performance Pac replaces the entire restrictive stock air intake system to unlock more power and efficiency. Roush says that installation is “quick and easy” and can be completed in under an hour with basic hand tools in your garage or driveway. For those worried about their warranty, the Performance Pac comes with a Roush three-year/36,000-mile Limited Powertrain Warranty.
Roush Performance Pac Level 1 is 50-state emissions-legal on 2018 through 2020 Mustangs. It also has a CARB E.O. number for California, #D-418-37. The Level 1 Performance Pac sells for $935. Those wanting to upgrade later can add the Roush cat-back exhaust pushing it to Level 2 performance. Roush says with the system installed, the four-cylinder Mustang is good for 296 horsepower and 349 pound-feet of torque, both significant gains from stock. Roush has been busy this week, announcing the availability of the 2020 Nitemare and F-150 SC pickups.
