Ramair Ford Focus ST 250 (MK3) 2012-2014 Air Intake Kit

Ramair Performance Air Intake Kit – Ford Focus ST 250 MK3 (2012-2014)

The Ramair JSK-115-BOLT is a complete performance air intake kit designed specifically for the Ford Focus ST 250 MK3, covering 2012 to 2014 models fitted with a bolt-in style IAT sensor (IAT stands for Intake Air Temperature – a small sensor that plugs directly into the intake pipe). If your car has a twist-type IAT sensor, a separate kit is available, so it is worth confirming your sensor type before ordering.

The standard air intake on the Focus ST is designed with cost and noise reduction in mind, which means airflow to the engine is more restricted than it needs to be. Replacing it with this Ramair kit opens up the breathing, allowing the 2.0-litre turbocharged engine to pull in air more freely. The result is improved throttle response – the engine reacts more quickly and cleanly when you press the accelerator – along with a more noticeable induction sound as the turbo spools up.

What is included in the kit

• Black powder-coated hard intake pipe
• Black powder-coated heat shield – helps keep hot engine bay air away from the filter
• Ramair foam air filter – a high-flow, reusable filter element
• Black silicone couplers – flexible joining pieces that seal the intake system
• Full fitting hardware and step-by-step instructions

What to expect from this upgrade

This is a well-regarded bolt-on upgrade for the MK3 Focus ST. You can expect a noticeable improvement in throttle response and a more engaging intake and turbo sound during acceleration. Modest performance gains are a realistic outcome, though the most significant changes most drivers notice are in the way the car feels and sounds rather than dramatic power figures on their own. For bigger power gains, this kit works well as part of a broader engine tune or modification package.

Installation is straightforward and does not require specialist tools. The included instructions guide you through the process, making this suitable for a competent home mechanic as well as a professional workshop.

Important fitment note: this kit (JSK-115-BOLT) is designed for Ford Focus ST 250 MK3 models with a bolt-in style IAT sensor only. It is not suitable for vehicles with a twist-type IAT sensor. Please use the vehicle lookup tool on this site or check the Vehicle Fitment tab to confirm compatibility with your specific car before purchasing.
