Product Details
Garrett Mustang EcoBoost Intercooler Kit 2.3L, Garrett 2015+ Ford Mustang 2.3L EcoBoost Air / Air Intercooler CAC (21.00inx5.32inx5.75in) - 600 HP
The 857564-6001 Honeywell Garrett intercooler directly fits the 2015+ 2.3L Ecoboost Mustang in the stock location and can support up to 600 horsepower. This 2.3L Mustang intercooler kit assembly leverages Honeywell Garrett’s extensive automotive and aerospace experience to offer the market a differentiated product.
The aluminum core features advanced offset fin design and vacuum brazed bar-and-plate construction resulting in superior thermal and fatigue performance. CFD optimized cast aluminum end tanks reduces recirculation and maximizes 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 Garrett Mustang Ecoboost 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.
Granted by the California Air Resource Board (C.A.R.B), executive order #D-794 allows the 857564-6001 Honeywell 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.
To maximize the available space and cooling potential, the Honeywell 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 Honeywell 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 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 Honeywell intercooler took 9 dyno pulls to heat saturate and reached a maximum outlet temperature of 154 degrees.
With the OE intercooler installed, the 2.3L engine produced 216HP at 5000 RPM. Honeywell's C.A.R.B. approved intercooler upgrade produced 237HP at 4891 RPM.
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 Garrett Mustang Ecoboost 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.

When you have determination and the expertise needed to succeed that is not necessarily the guarantee of success especially in a competitive market like the aftermarket performance parts industry. But this is just what the founder of HONEYWELL GARRETT accomplished at his small, unpretentious office in Los Angeles. Having established itself as a significant player in the turbocharge and intercool business the company has grown from its meager beginnings to a company that offers a product that is produced by no less than six thousand employees and that is no insignificant accomplishment.
Cliff Garrett knew what he wanted to create and he did just that and consequently can proudly tout the servicing of some of the most renowned engine and vehicle manufacturers. Names such as Audi, BMW, Daimler-Chrysler, DDC, Fiat, Ford International Truck Company, Peugeot, Renault, Saab and Volkswagen are among HONEYWELL GARRETT’S customer base.
The HONEYWELL GARRETT company’s prominence in the turbocharge industry is a result of a significant number of industry firsts; such as its celebrated dual-ball bearing turbo designed for high performance vehicles. Accomplishments such as these are the reason HONEYWELL GARRETT is the preferred turbocharger of the most prominent original equipment manufacturers and of such well known top racing teams in races like CART, World Rally, American Le Mans, 24 Hours of Lemans and Pikes Peak to name a few.
And let’s not forget that important part, the intercooler, whose job it is to cool the air compressed by the turbo charger, significantly reducing its temperature and consequently increasing the density of the air supplied in the engine. In high performance cars like the Mustang this is a necessary addition to your achieving your performance goals particularly when the HONEYWELL GARRETT EcoBoost Intercooler can support up to a whooping 600 horsepower. It takes a company with capacious experience in both the automotive and aerospace field to offer you such an individualized product such as the Ecoboost Mustang intercooler.
With such characteristics as an advanced offset fin design and vacuum brazed bar and plate construction you are assured of top notch thermal and fatigue performance. These things coupled with an ease of installation requiring only basic hand tools and an ability to reuse your factory hoses, clamps and bolts make it the perfect choice when it comes to an intercooler. When you install the complete assembly you can expect to see results in reduction in pressure drop by up to thirty percent and a reduction in up to forty percent in charge air temperature.
Another reason to trust your Mustang to a HONEYWELL GARRETT intercooler is its long affiliation with some ot the foremost names in the high performance automobile industry. Names like Roush, Saleen, Mercedes-Benz, AMG, Ford SVT, GM and McLaren incorporate the HONEYWELL GARRETT intercooler in their hottest models.
It is extremely important to protect your car from the fatigue that can be caused by the high boost pressures and temperatures in today’s extreme engine. The GARRETT intercooler with its top quality material and advanced designs that assures of outstanding heat transfer and durability can accomplish this goal for you and you can feel confident in your choice because GARRETT has a proven track record in the industry when it comes to intercoolers.
