Why Upgrade the Factory Focus ST Intercooler?

One of the most common complaints among tuned Focus ST owners is heat soak.

After repeated pulls, many drivers experience:

• Reduced power
• Higher intake temperatures
• Timing correction
• Slower acceleration

The factory intercooler becomes increasingly restrictive as boost levels rise.

Compatible with the 2013+ Ford Focus ST with no modification to front bumper and retains stock fog lights. Core Size- 26.1 x 4.2 x 8.2 inches

Supports Up To 550 WHP

One of the standout features of the Mishimoto kit is its impressive power capacity.

Horsepower Rating

• Supports up to 550 wheel horsepower

This makes the intercooler suitable for:

• Stage 1 builds
• Stage 2 builds
• Big turbo setups
• E30 and E85 tuning combinations

Even if your current Focus ST isn’t making anywhere near 550 WHP, having room to grow is never a bad thing.

Massive 4.3-Inch Core Design

Core Dimensions

• Length: 26.1 inches
• Height: 8.2 inches
• Thickness: 4.3 inches

The thicker core provides:

• Increased thermal capacity
• Better heat dissipation
• Improved cooling efficiency
• Greater resistance to heat soak

No Front Bumper Modification Required

Unlike some oversized intercoolers that require cutting or trimming, this Mishimoto kit:

Installation Benefits

• No bumper modification required
• Retains stock fog lights
• Direct-fit design
• Factory-style appearance

This makes installation much cleaner and easier.

Improved Hot-Side Pipe Flow

The included hot-side pipe offers:

Performance Improvements

• 26% greater airflow than stock
• 14% more volume than stock

Benefits include:

• Reduced restriction
• Improved boost response
• Better airflow efficiency

Improved Cold-Side Pipe Flow

The cold-side pipe delivers even greater improvements.

Performance Improvements

• 40% greater airflow than stock
• 10% more volume than stock

This helps maximize airflow between the intercooler and throttle body.

Why Larger Pipes Matter

Factory piping often becomes restrictive as horsepower increases.

Upgraded intercooler piping can help:

• Reduce pressure drop
• Improve airflow efficiency
• Support higher boost levels
• Improve turbocharger response

Better Resistance to Heat Soak

Heat soak is one of the biggest enemies of turbocharged performance.

Benefits of the Mishimoto intercooler include:

• Lower intake temperatures
• Improved consistency
• Reduced timing pull
• Better repeatability

This is especially noticeable during hot summer driving and track use.

Perfect for Tuned Focus ST Builds

Common modifications include:

• ECU tuning
• Downpipes
• Intake systems
• Larger turbochargers
• Ethanol blends

As power increases, efficient charge-air cooling becomes increasingly important.

Great for Daily Drivers

Even stock or lightly modified Focus ST models can benefit from:

• Improved thermal management
• More consistent power delivery
• Better hot-weather performance
• Enhanced reliability

Excellent for Track Use

Road Courses

Maintains power throughout long sessions.

Autocross

Improves consistency between runs.

Roll Racing

Supports repeated high-speed pulls.

Canyon Driving

Reduces performance loss from heat buildup.

Frequently Asked Questions

Does this fit every Focus ST?

Yes, it is designed specifically for 2013+ Focus ST models equipped with the 2.0L EcoBoost engine.

Will it fit a Focus RS?

No. The Focus RS uses a different intercooler configuration.

Do I need a tune?

No. The intercooler can be installed on a stock vehicle, although tuned vehicles typically see the greatest benefits.

Why are upgraded pipes included?

The upgraded piping increases airflow capacity while reducing restrictions found in the factory system.

Final Thoughts

The Mishimoto MMINT-FOST-13KBSL Performance Intercooler Kit is one of the most comprehensive cooling upgrades available for the Ford Focus ST. With support for up to 550 WHP, a massive 4.3-inch core, and upgraded piping that dramatically improves airflow, it provides everything needed to combat heat soak and support serious performance goals.

Because nothing ruins a perfectly tuned Focus ST faster than watching intake temperatures climb while the turbo is still trying its hardest.
