7 Upgrades to Make on Your Ford Focus ST

The Ford Focus ST is a great choice for the performance enthusiast who wants to do their own upgrades or pay a company to take care of it for them. While there are several modifications that can be made to this vehicle, we’ve listed the top seven below.

COBB Tuning Intercooler Hose Kit

An intercooler is a component that sits between your engine and turbocharger. As hot turbocharged air heads toward the engine, the intercooler brings the temperature down making it less harmful to your engine components. An intercooler is basically a radiator that cools the air before it’s fed into the engine. The result is a denser charge of air, which improves performance. It’s one of the must-have Ford Focus ST mods when upgrading your car’s performance. The nice thing is that you can get these kits from COBB tuning for a variety of different cars and engines.

New Wheels and Tires

The wheels and tires on your car are the only part that comes in contact with the road. They’re also one of the most expensive components on your vehicle. This is why it’s important to make sure you choose the best ones possible. Tires play an integral role in handling and safety, as well as fuel economy. If you’re looking to improve your Focus ST’s performance or increase its lifespan, upgrading these components may be worth it. The right tires can improve traction, reduce noise levels, and even improve fuel economy.


A muffler is an important component in your engine’s exhaust system, and it can be a great way to upgrade your Ford Focus ST. A new muffler will keep the sound of your car at a comfortable level while improving performance. You can find this part at a local auto parts store or online. Muffler upgrades can add horsepower and torque by allowing more air into the engine. They also ensure that all of the gasses inside exit smoothly as they leave through the exhaust pipe.


If you want to get more out of your engine, a tune is a way to go. It can help you get more power out of it and improve gas mileage. Tunes are also a great way to optimize performance. They can also make sure that all of the components in your car are working together correctly.

Exhaust System

Exhaust systems are designed to reduce the sound of a car’s engine and prevent it from polluting the environment. They also improve performance by reducing pressure. The exhaust system includes the exhaust manifold, the catalytic converter, the O2 sensor, the muffler, the resonator, and the exhaust pipe. Each of these parts has a unique role to play. For instance, the catalytic converter takes harmful carbon emissions and converts them into less harmful gasses while the muffler takes the sound from the engine and dampens it to make it less noisy.

If you want to improve the performance of your Ford Focus ST, you can make upgrades to these components. If you do, you can increase horsepower or torque output, you can improve fuel economy, and you’ll experience faster acceleration times thanks to better engine breathing capabilities. This happens when you remove restrictive stock parts like catalytic converters or mufflers. Just a few mods can really bring this car to life.

COBB Turbo Heat Shield Blanket

The Cobb Turbo Heat Shield Blanket is a simple and effective way to protect your Ford Focus ST’s turbocharger and engine from overheating. Too much heat can lead to a variety of problems including decreased performance, reduced boost response, and even turbo failure. The Cobb Turbo Heat Shield Blanket provides effective protection for your car’s turbocharger by covering it in an insulating layer that reduces heat transfer from the turbocharger to the engine. This keeps temperatures lower than they would be without installing a heat shield blanket.

Upgrades Can Improve Visual Appeal

A new paint job, different tires, and even under-the-car lights can make your car more unique and increase its visual appeal. Other upgrades can also make your car perform better. For some, their car is an extension of their likes and dislikes, so it’s important to make upgrades that you love, not just ones that others have. Use colors and styles that appeal to you so that your car is as unique as you are.
