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 intercooler 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 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.

  •  Optimized Performance:

    Temperature regulation is crucial for power production and delivery. When engine or charge temperatures rise too high, your vehicle automatically limits power output to prevent damage. This applies to both stock and tuned vehicles.

     

    Enhanced Efficiency: 

    Upgrading the stock intercooler helps maintain lower charge temperatures for extended periods. This means your engine can operate at peak efficiency longer, minimizing power limitations due to high temperatures.
