What are the best performance upgrades for a Ford Fiesta ST?

I recently purchased a Ford Fiesta ST and I'm looking to upgrade its performance. What modifications can I make to increase horsepower and improve handling? Any advice would be greatly appreciated!

Congratulations on your new Fiesta ST! One of the first upgrades I would recommend is a cold air intake to increase air flow to your engine. You can also upgrade to a high-flow exhaust system to improve horsepower and sound. Additionally, consider installing a performance chip to optimize your engine's performance.

Don't forget about suspension upgrades! Upgrading to better shocks, springs, and sway bars can greatly improve your Fiesta ST's handling and cornering capabilities. And for even more power, a turbo upgrade can give your car a significant boost.

Another great way to boost performance is by upgrading to a larger intercooler. This will help keep your engine cool and prevent heat soak, resulting in better performance. And don't forget to invest in a high-performance tune to optimize your car's power and torque.
