Wagner Tuning Ford Focus ST MK4 2.3 Ecoboost Competition Intercooler Kit

This is the Wagner Tuning Competition Intercooler Kit specifically for the Ford Focus ST MK4 equipped with the 2.3L Ecoboost engine. If you're pushing your Focus ST hard, especially with performance tuning, managing intake air temperatures is crucial for consistent power. The stock intercooler can struggle to keep up, leading to heat soak and reduced performance. This kit replaces the factory unit with a much larger, more efficient design to help keep your engine's air charge cooler.

Wagner Tuning builds this intercooler with a high-performance bar-and-plate core. This type of core offers a larger surface area and better thermal capacity compared to tube-and-fin designs, meaning it can dissipate heat more effectively. The end tanks are made from cast aluminum and are designed to optimize airflow into and out of the core, minimizing turbulence and pressure drop. This improved airflow and cooler charge air translates to more reliable power, especially during extended driving sessions or track use. The kit is designed as a direct replacement for the factory intercooler, simplifying the installation process. It includes all the necessary components for a complete installation, such as silicone hoses and mounting hardware.

When installing this intercooler, you'll want to ensure all connections are secure to prevent boost leaks. Because this is a larger unit, some minor adjustments to surrounding components might be needed, but it's designed to fit without major fabrication. This intercooler is a popular choice for Focus ST owners looking to unlock more consistent performance from their tuned vehicles.
