Garrett 15+ EcoBoost Mustang Upgraded Intercooler


PD Notes: Intercoolers are one of the first mods we recommend to people that are looking to mod their Ecoboost. The factory units are woefully inadequate and can heat soak very easily. It is very common for an Ecoboost with a factory intercooler to see 150+ degree charge temps after one 3rd gear pull. This is with outside temperatures being in the 90’s. Generally your street intercoolers (made by cv fab, garret, cobb, etc.) are a direct replacement for the factory intercooler while retaining the factory grill shutters. These tend to work well for the everyday car below 500hp that doesn’t do any real track racing, or extended high speed pulls. For vehicle in more extreme climates, wanting to make big power, or vehicles that are going be doing track day sessions we highly recommend the larger Race intercooler we sell, or adding methanol injection to your vehicle to drop your charge temperatures below ambient. 

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 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 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.
