Performance Pacs – Delivering Performance Parts Customers Can Trust

Whether you’re a veteran performance vehicle enthusiast or just getting started, there is one thing we are all looking for – MORE POWER! Horsepower is essentially the Holy Grail of the performance automotive industry, or at the very least the little golden idol from the beginning of Raiders of the Lost Ark. Rest assured, thanks to our ROUSH Performance Pacs, you won’t have to worry about traversing booby trap-laden caves to earn some extra horses.

The ROUSH Performance Pac line works by replacing the restrictive factory air intake system with our Cold Air Intake Kit and pairing it with a specially tuned ROUSH Calibration. Our Level 1 Performance Pacs unleash an additional 24 rear-wheel HP on Mustangs and 18 horsepower over the stock 5.0L V8 F-150 – making these kits a wallet-friendly option for those who aren’t ready to take the plunge on a supercharger We have Raptor owners covered too, as the 2019 Raptor Performance Pac adds 71 horsepower and 55 ft-lb torque over the stock 3.5L EcoBoost F-150 and 57 horsepower and 73 ft-lb torque over the stock 3.5L (HO) Raptor. These kits also provide improved throttle response and enhanced sound with the Level 2 kits.

What comes in a Performance Pac?


The cornerstone of the Performance Pac line is the upgraded engine calibration. The technical experts on our engineering team go to great lengths to generate more power with the vehicle’s existing hardware, while maintaining the reliability and drivability that you have come to expect from ROUSH.

It can be difficult to imagine the work that our engineering team does to ensure customers are getting the most out of these F-150 and Mustang tunes. Would it be easier to just throw a Performance Pac-equipped vehicle up on the dyno and call it a day – of course, but that’s not the way we do things here at ROUSH. Our performance tunes are tested all over the country in just about every conceivable scenario. This means our engineering team takes these cars to the desert to test in extreme heat, to Minnesota to test in extreme cold and snow, and to the mountains to test performance in high-altitude scenarios. Thanks to 2,240 hours of testing, the bottom line is that when a customer purchases a ROUSH Mustang or F-150 Performance Pac, they can rest assured that it will perform at a high-level no matter the situation.

Installing the calibration may require dealer assistance, but don’t worry, we have you covered. You can use the ROUSH Performance dealer search tool to locate your nearest authorized ROUSH parts dealer.

Cold Air Intake

ROUSH engineers use their extensive expertise in powertrain development to optimize the flow of air into the engine, while minimizing intake air temperatures (yielding in more dense oxygen levels and thus more power). On top of the performance upgrade offered by ROUSH CAI’s, our dry filter is proven to retain its shape under high airflow and is composed of an inner and outer layer of wire mesh to ensure durability. Additionally, the filter requires no oiling and is easily washable for re-use.

Level 2 Mustang and F-150 Performance Pacs up the ante by bringing exhaust upgrades into the mix, adding aggressive sound to the upgraded power. ROUSH exhaust kits are made from premium materials and feature mandrel-bent tubing to increase exhaust gas flow and reduce backpressure.

On or off the road, you can feel confident that ROUSH Performance will provide top-tier performance parts to your Mustang and F-150. Hundreds of engineering hours went into designing and testing the perfect CAD-matched fit, feel, and finish of this kit for a simple and smooth installation.
