ECS Upgraded Front Mount Intercooler - Cast Aluminum - MINI Cooper S/JCW

This ECS intercooler replaces the stock MINIature intercooler with a MASSIVE 250% larger surface area and a 125% thicker base core! This increase in core size improves flow while cooling compressed air into the intake manifold. Cast aluminum end tanks are TIG welded and feature machined transitions for maximum flow. This intercooler features a special black powder coating to prevent fin corrosion, as well as improve overall heat transfer to insure the lowest possible outlet temperatures.

FEATURES:

250% larger surface area compared to the OEM intercooler 125% thicker intercooler core TIG welded transitions Flat black powder-coated finish BENEFITS:

Drastically lower intercooler outlet temperatures/intake air temperatures Increased airflow Reduces the likelihood of heat soak DESIGN:

The limitations of the stock intercooler were apparent throughout our testing and design process. The stock part consistently struggled to manage charge air temperatures, even under normal driving conditions. Our ECS Intercooler has been designed to improve on every restrictive element of the stock cooler, enhancing cooling efficiency by lowering intake air temperatures even compared to the R56 Cooper S aluminum intercooler, allowing you to continuously push your car without the detriment of heat soak!

This ECS Front Mount Intercooler Kit was designed, engineered, tested, and quality inspected by our Research and Development team at our Wadsworth, Ohio facility. We strive for the highest level of precision and quality through leading-edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

NOTE: A performance tune is not required to run this intercooler. A tune will only increase the output of the engine when equipped with this intercooler.

**Some Prefacelift & GP2 models require slight modification inside the front bumper**
