The stock 2.3L pulls 236kW and 448Nm from its engine, shared with the Focus RS, but with a Roush Performance Pac the Mustang gains 25kW and 50Nm, for a total 261kW/498Nm. Focus, eat your heart out.
Roush achieves the power up though a conceptually simple method – an intake upgrade. Okay so it’s a little more complex than that, there’s a tune involved so chances are it’s not something you can do as a home job.
Enter Melbourne-based workshop Mustang Motorsport, which can install and tune the Roush Performance Pac.

Roush also offers a second level of the kit, which includes a dual-exit axle-back exhaust. Mustang Motorsport doesn’t offer this, as Aussie cars already get a dual-exit exhaust, so the intake upgrade and tune is the only change that will make a difference.

In the US, the Performance Pac level 1 costs USD$935, which converts to AUD$1415. Mustang Motorsport doesn’t have a publicly listed price, but parts and installation could vary for different variations of four-cylinder Mustangs.
