Product Description

Mustang GT Roush Stage 1 Performance Pac
Upgrade the performance in your 2015-2017 Mustang GT with this Stage 1 Performance Pac from Roush! Your Mustang's stock air intake is restrictive and is holding you back from increasing the power. This ROUSH cold air kit is fully tested and calibration certified to work seamlessly with the performance ECU reflash. Adding this kit not only improves horsepower & torque throughout the entire power band, but gives you better throttle response as well! With this Roush Stage 1 Performance Pac you will be looking at increases of over 25 RWHP and 30 lb-ft RWTQ, by simply bolting it on and uploading the tune!

Roush Calibration
Roush calibration engineers have extensive OEM calibration experience to ensure strong performance without sacrificing driveability. Their calibrations are developed with hundreds of hours spent in the lab and on the dyno, testing, and validating their calibrations, setting this Performance Pac apart from needing any guesswork tuning! Included in this Performance Pac is the dongle, which allows for the ability to easily “flash” the vehicle's PCM at home, avoiding a visit to a Ford dealership, or other ROUSH dealer.

Roush Quality
Roush Performance builds all of their parts to OEM standard for the best fit, finish, and performance. This S550 cold air intake is no exception. Using computer-aided design (CAD), this Roush cold air intake kit is designed as a direct fit installation, and is optimized for a complete hood seal with no cold air loss. A dry filter is utilized to retain its shape under high airflow. Wire mesh inner and outer layers provide durability, and the highest filtration possible. No oiling is required, and is easily washable for re-use!

- NOT for sale in California or states that require California E.O.
- This Performance Pac is NOT designed to be compatible with other aftermarket powertrain components!
