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 & 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 & 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.
Note: Not approved for sale or installation in California or states that require an EO number.
Note: For owners of 2015+ Mustangs that are equipped with ROUSH’s quad-tip exhaust, ROUSH recommends you go with the Level 1 Performance Pac, as the exhaust in this system cannot be used on your vehicle.
