Do you have a 2015-2017 Mustang with the I4 2.3L EcoBoost engine and want the most power ROUSH Performance has to offer? You came to the right place!

The Roush Performance “Level 2” Performance Pac for the 2015+ 2.3L I4 EcoBoost Mustangs adds a staggering 60 RWHP and 51 lb-ft. of torque to the stock 2.3L Ecoboost engine! Included in this Performance Pac will be the ROUSH Performance Cold Air Intake for the 2015+ 2.3L I4 Mustang, the ROUSH Axle-Back Round Tip 304SS Exhaust System for the 2015-2017 2.3L I4 Mustang , and a ROUSH Re-Calibration for the vehicle’s PCM (details seen below). As if that wasn’t enough, an optional 3-year/36,000-mile ROUSH Limited Powertrain Warranty gives you confidence to crank up the power!

Our cold air kits are the best in the industry, designed and tooled using factory CAD data to maximize available under-hood space, and injection molded from premium automotive grade materials for long life. An incredible 75% lower intake restriction over stock ensures you will never need to upgrade your intake.

The ROUSH premium 2.5” axle-back round tip exhaust system included is built from high-quality 304 grade stainless steel for long life and great sound. Included are 2 polished round tips (which are embossed with the ROUSH logo), all necessary hardware, and instructions for cutting and installation.

Roush calibration engineers have extensive OEM calibration experience and sweat the details to ensure strong performance without sacrificing drivability. Hundreds of hours spent in the lab and on the dyno, testing and validating rigorously, set our ROUSH calibrations apart from “guesswork” tuning found in other kits.

In addition to improved horsepower and torque, our kit also provides improved boost and throttle mapping that will lend a “sportier” feel right off idle to provide amazing drivability improvements all through the power band.

The ROUSH calibration in this Performance Pac is easily programmed into the ECU of the vehicle via an industry standard J2534 tool and our free Roush Diagnostic Tool (RDT) software.

Included dongle allows for the ability to easily “flash” the vehicle's PCM at home, avoiding a visit to a Ford dealership or other ROUSH dealer.
