An intercooler cools the compressed air coming off the turbo before it reaches the engine. This is a direct-fit replacement for the factory intercooler on the first-generation (2014-2019) Ram 1500 EcoDiesel - the older DS-body truck, sold as the "Ram 1500 Classic" once the new-body DT truck launched for 2019. It is a factory-style replacement, not a performance upgrade.
why this one — This is the straightforward fix when a worn or damaged factory intercooler needs replacing on an older EcoDiesel: same core size and tube/fin design as stock, aluminum core, bolts up to the factory hoses and brackets with no modification, and CSF backs it with a 1-year warranty.
CSF describes this as meeting or exceeding OE cooling standards with improved burst-pressure capability over a worn stock unit. No dyno hp/tq figure or specific temperature-drop number is published.
