Garrett Motion 2015-2022 Ford Mustang Ecoboost Front Mount Intercooler

Garrett intercoolers offer superior fatigue protection for the high boost pressures and temperatures of today’s extreme engines

The 857564-6001 Garrett intercooler directly fits the 2015+ 2.3L Ecoboost Mustang in the stock location and can support up to 600 horsepower. This intercooler assembly leverages Garrett’s extensive automotive and aerospace experience to offer the market a differentiated product.

The aluminum core features an advanced offset fin design and vacuum brazed bar-and-plate construction resulting in superior thermal and fatigue performance. CFD optimized cast aluminum end tanks reduce recirculation and maximize flow. The complete assembly results in up to a 30% reduction in pressure drop and up to a 40-degree reduction in charge air temperature.

The intercooler installs in two and a half hours using basic hand tools and can reuse the factory hoses, clamps, and bolts. Slightly elongated inlet and outlet ports create a secure surface for hose attachment reducing the chance of detachment on higher horsepower applications while maintaining compatibility with OEM hoses and aftermarket charge pipes.

Available Now: Intercooler upgrade for the 2.3L Ford Mustang

[/ux_text]
[ux_text text_align=”left”]

Granted by the California Air Resource Board (C.A.R.B), executive order #D-794 allows the 857564-6001 Garrett intercooler upgrade to be used on specific emission controlled vehicles. California is the only state that is permitted to issue emissions standards with an approval form the Environmental Protection Agency. Obtaining a C.A.R.B certification identifies this intercooler will not increase vehicle emissions.

Computational Fluid Dynamics (CFD) is a process that uses numerical calculations to simulate movement of gasses through defined boundaries and various conditions. Supercomputers take days to perform each analysis and have become a standard process used when developing Garrett thermal products.

Superior Fatigue Performance

[/ux_text]
[ux_text text_align=”left”]

To maximize the available space and cooling potential, the Garrett intercooler core is 60% larger than stock and features advanced offset fin design and vacuum brazed bar-and-plate construction resulting in superior fatigue performance and up to a 40 degree reduction in charge air temperature.

A stock 2016 2.3L EcoBoost Mustang was used to perform consecutive dyno pull comparisons to simulate on-track conditions with the Garrett intercooler and the OE intercooler. In the chart above, each peak represents one dyno pull. The top peaks show inlet air temperatures which remain consistent around 275 degrees while the bottom peaks reflect outlet air temperatures going into the engine.

Heat/soak saturation

[/ux_text]
[ux_text text_align=”left”]

Heat soak/saturation identifies the limit at which an intercooler can no longer reduce charge air temperatures going into the engine. Looking at the chart we can see that both intercoolers reach heat saturation at significantly different times and significantly different temperatures.

Based on this test, the OE intercooler reached a max outlet temperature of 183 degrees during its fourth pull; whereas the Garrett intercooler took 9 dyno pulls to heat saturate and reached a maximum outlet temperature of 154 degrees.

The graph depicts horsepower and torque at full heat saturation. With the OE intercooler installed, the 2.3L engine produced 216HP at 5000 RPM. Garrett’s C.A.R.B. approved intercooler upgrade produced 237HP at 4891 RPM.

Intercooler upgrade

[/ux_text]
[ux_text text_align=”left”]

Increasing the efficiency of the air cooling system enables the engine to produce higher peak values during the hottest conditions by delivering cooler air to the engine and prolonging the negative effects of heat saturation. This intercooler upgrade installs in two and a half hours using basic hand tools and reuses the factory hoses, clamps, and bolts. Elongated inlet and outlet ports create a more secure surface for hose attachment reducing the chance of detachment on higher horsepower applications while maintaining compatibility with OEM hoses and charge pipes.

Frequently Asked Questions

How long does it take for my parts to ship?
If it’s in stock and ready to roll, your order usually hits the road within 1–3 business days.

For made-to-order or specialty items (like carbon fiber parts or custom builds), the turnaround can take up to 8 weeks — perfection takes time.

Either way, we’ll keep you updated so you know exactly when your parts are leaving the pit lane.
Do you send tracking with my order?
Absolutely. Once your order ships, you’ll receive an email with a tracking link so you can follow its journey from our shop to your doorstep.

If your order ships via freight, you’ll get a separate email with a direct link to the carrier’s tracking page — easy and stress-free.
