Product Description
The MK3 Ford Focus RS is perfect for weekday commutes and thrilling track days. Its 2.3L Turbo engine delivers impressive power, but the stock tube-and-fin intercooler struggles to keep up, especially when adding a tune or bolt-on upgrades. This can lead to heat soak, which limits performance. To solve this, Injen offers the FM9003i Front Mount Intercooler, designed specifically for the Focus RS MK3. This bar-and-plate intercooler efficiently reduces charge air temperatures, improves airflow, and minimizes pressure drop. With factory calibrations pulling timing as temps rise above 100 degrees, upgrading to this intercooler ensures consistent power by maintaining near-ambient charge air temperatures.
The FM9003i intercooler boasts a 25% increase in core volume and reduces charge air temps by an average of 35%, delivering gains of up to 14 HP and 15 Ft. Lbs. of torque. Built with cast end tanks, precision CNC-machined flanges, and TIG-welded construction, it integrates seamlessly with factory piping. Its brushed aluminum-like silver finish adds a sleek touch under the hood. Easy to install in about an hour, this intercooler is a reliable upgrade for both stock and modified Focus RS models. With enhanced performance, durability, and a Lifetime Warranty, the Injen FM9003i is an essential addition for maximizing your Focus RS experience.
