Roush Performance Engineering is showing the Ford Mustang EcoBoost some love with a new pair of performance upgrade kits designed to help get the most out of the factory 2.3L turbo motor. Both packages - the Roush Performance Pac Level 1 and Performance Pac Level 2 - add just over 30 horsepower to the 2018+ EcoBoost Mustang's factory 310-horsepower peak, along with a 37-lb-ft bump to peak torque, the difference being whether or not a Roush axle-back exhaust kit is included.

Sadly for folks with the EcoBoost High Performance Package, Roush's performance-enhancing kits aren't compatible, as that factory package uses a detuned version of the Focus RS's optimized, power-dense mill.

But if you were wondering what it takes to increase the regular EcoBoost mill's output to near that of the 350-horsepower Focus RS, the answer is: not much. Roush's Performance Pac Level 1 for the 2018+ EcoBoost Mustang feature a cold air intake with a washable dry element performance air filter, an engine control unit reflash, and that's it. Level 2 adds in a signature Roush exhaust system with high-flow mufflers and dual-wall exhaust tips - a combo that does little for peak power, but plenty for the EcoBoost engine's growl.

Both kits come with a 3-year/36,000-mile Roush limited powertrain warranty.

The common consensus among the Mustang faithful has long been that the V8 is the quintessential pony car engine, rendering Ford's 2.3L EcoBoost four-cylinder somehow unworthy the same respect as Ford's 5.0L Coyote. Yet there's something to be said for an engine that can put out near-V8 levels of power with half as many cylinders, a turbocharger, and a couple of simple modifications. The smaller engine means less weight over the front axle of the car, too, meaning a preferable front-to-rear weight distribution.

Now, with Roush's Level 1 and 2 Performance Pacs for the four-cylinder Mustang, EcoBoost fans have two more reasons to brag.
