Do you have a Mustang with the I4 2.3L EcoBoost engine and want some more power without spending a fortune? You?re in luck! The Roush Performance ?Level 1? Performance Pac adds exceptional horsepower and torque to the stock 2.3L engine. Included in this Performance Pac is a ROUSH Cold Air Intake and a ROUSH Re-Calibration for the vehicle?s PCM. Our cold air kits are 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. 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, improved boost and throttle mapping will lend a ?sportier? feel right off idle to provide amazing drivability improvements all through the power band. Do you already have a ROUSH Mustang Axle-Back Exhaust installed? Adding this Level 1 Performance Pac to your existing setup will yield the equivalent of our ?Level 2? Performance Pac System (60 RWHP/51 RWTQ)! The ROUSH calibration is easily programmed into the ECU of the vehicle via an industry standard J2534 tool & our free Roush Diagnostic Tool (RDT) software (note: dealer service charges may apply). Most dealers, should they be equipped with the proper tool, can complete the calibration process in under an hour. Note: 2015+ Mustangs equipped with ROUSH?s quad-tip exhaust, ROUSH recommends the Level 1 Performance Pac, as the exhaust in this kit cannot be used on your vehicle. An optional 3-year/36,000-mile ROUSH Limited Powertrain Warranty gives you confidence to crank up the power!
