How Can I Improve the Performance of My Ford Focus ST?

I recently purchased a Ford Focus ST and I'm looking for ways to boost its performance. Are there any upgrades or modifications I can make to get more power and better handling? Any specific brands or parts I should consider?

One of the easiest ways to improve the performance of your Ford Focus ST is to upgrade the air intake system. Look into getting a high-flow air filter and a cold air intake kit from reputable brands like K&N or AEM. This will allow more air to flow into the engine, resulting in increased power.

Another upgrade to consider is a performance exhaust system. This will not only give your car a sportier sound, but also increase horsepower and torque. Look for cat-back or turbo-back exhaust systems from brands like Borla or Magnaflow.

Upgrading the suspension can also greatly improve the handling of your Ford Focus ST. Look into getting coilovers or lowering springs from brands like H&R or Eibach to reduce body roll and improve overall handling.
