On turbo-charged cars like the Focus ST, getting more air to the engine is a great way to increase horsepower. Many Focus ST factory components don't allow air to move as efficiently as it should through the Focus ST’s engine, which ultimately limits the performance.

A Focus ST cold air intake helps bring cooler air into the engine, resulting in power improvements you can feel and hear. An aftermarket cold air intake has larger piping and higher quality filters compared to the factory unit. So if you're looking for an easy way to improve power and throttle response, a Focus ST cold air intake is a great place to start. Pair a new Focus ST air intake with a cat-back exhaust kit and a Focus ST engine tune to maximize your horsepower.
