46% Increase in Core Volume and 128% Greater External Surface Area
Compared to the factory intercooler, Mishimoto’s design features a 46% larger core and 128% more external fin surface area. This means dramatically improved heat transfer and lower intake air temperatures (IATs) across the rev range.
On average, this intercooler can deliver intake temp drops of up to 35°F (19°C), ensuring consistent power delivery even during spirited driving or track sessions. That translates to more horsepower, better throttle response, and reduced turbo lag.
High-Quality Aluminum Bar-and-Plate Construction
The MMINT-FOST-13KBSL is built using a 100% aluminum bar-and-plate core, offering superior durability, heat resistance, and efficiency. Unlike cheaper tube-and-fin designs, this construction resists heat soak and maintains cooler intake temps during sustained boost.
The end tanks are precision TIG-welded and designed to withstand high boost pressures — perfect for enthusiasts running performance tunes or upgraded turbos.
The sleek silver powder-coated finish not only enhances corrosion resistance but also adds a professional, performance-ready look visible behind your Focus ST’s front bumper.
Improved Airflow and Turbo Efficiency
By minimizing restriction and improving flow efficiency, the Mishimoto intercooler helps your turbo work less to achieve the same boost levels — resulting in faster spool, better throttle response, and reduced strain on your turbocharger.
When paired with Mishimoto’s performance intercooler piping, this kit ensures smooth airflow from turbo to throttle body, eliminating unnecessary turbulence and pressure loss.
Direct-Fit Installation — No Cutting or Trimming Required
Mishimoto designed the MMINT-FOST-13KBSL for a bolt-on installation using factory mounting points. That means no cutting, trimming, or fabrication — just a straightforward upgrade that fits perfectly in your Focus ST.
All necessary hardware is included, and the kit works seamlessly with both stock and Mishimoto intercooler piping. Installation typically takes under two hours with standard tools.
Dyno-Proven Performance Gains

Final Thoughts

With dramatically improved cooling capacity, enhanced turbo response, and durable construction, it’s built for drivers who demand real performance from their EcoBoost engine.

It’s time to cool off your hot-hatch with the Mishimoto Performance Intercooler Kit for the 2013+ Ford Focus ST. Ford released their 2.0T EcoBoost-powered Focus boasting the perfect combination of performance and practicality, however, the intercooling system left something to be desired. While the piping did feature sections of aluminum, the restrictive diameter and turbo muffler put a damper on the Focus ST’s performance potential. We’ve replaced the hot-side pipe with mandrel-bent aluminum, both ditching the muffler and opening up the diameter to allow a 26% better flow through the hot-side. All of the degradation-prone rubber has also been swapped for wire-reinforced silicone, ensuring a long-lasting connection on the hot-side and a smoother flow through the cold-side pipe. Together the Focus ST Intercooler Pipe Kit grants a 21% increase in flow to and from the intercooler. The piping isn’t the only part of this kit that increases flow. The bar-and-plate construction opens air channels within the core, allowing for the charged air to pass through more freely than the stock intercooler core. This upgraded all-aluminum construction aids in heat dissipation, warding off the dreaded heat-soak under demanding driving conditions, and delivering properly cooled air through the ST’s intake manifold. The Focus ST Performance Intercooler Kit will also add 8 HP and 10 TQ to your power band and has a maximum horsepower rating of 550HP. The Mishimoto Performance Intercooler Kit for your 2013+ is available in silver, black, or gold, with an option of wrinkle black or polished piping. As always, this intercooler kit is covered under the Mishimoto Lifetime Warranty.
