Description
The Mishimoto MMINT-MUS4-15SL is a purpose-built intercooler engineered exclusively for the 2015-2023 Ford Mustang EcoBoost, the first turbocharged 4-cylinder Mustang in over 30 years to produce over 300 horsepower. Where the factory tube-and-fin cooler heat soaks after just a few hard pulls, this Mishimoto bar-and-plate core is built to hold intake air temperatures down lap after lap, run after run. It’s a direct-fit unit that requires no modification to install.
As a forced induction component, this intercooler is central to keeping a turbocharged induction system performing consistently under repeated boost. Turbocharged engines generate extremely hot charge air quickly, and any forced induction setup is only as strong as its ability to shed that heat before it re-enters the engine. Mishimoto’s performance induction cooler addresses that head-on with a 58-percent increase in core size, a 25-percent increase in internal core volume, and a 165-percent increase in external fin surface area compared to stock, reducing intake air temperatures by 35°F (19.45°C) with minimal pressure loss. Cast, CFD-tested end tanks and an in-tank air diverter on the hot side keep airflow moving efficiently through the core, so the force induction system delivers cooler, denser air run after run rather than fading as the session goes on.
Vehicle Applications
This intercooler is a specific-fit part engineered for the 2015-2023 Ford Mustang EcoBoost and 2015-2023 Ford Mustang EcoBoost Premium, both built on the S550 chassis with the 2.3L EcoBoost engine. Mishimoto’s engineers designed it to mount in the stock location, working with the factory active grille shutters and avoiding airflow blockage to the radiator and AC condenser, so fitment on these model years is a bolt-on affair with no bumper cover removal required.
