Valeo 817653 Intercooler

OE Charge Air Cooler for Golf and Jetta

The Valeo Intercooler, part number 817653, is a direct replacement charge air cooler for select 2006 Volkswagen Golf and 2006 Volkswagen Jetta applications. It cools compressed turbocharger air before it enters the engine, helping maintain charge-air density and supporting stronger engine output.

Built as part of the Valeo OE line, this intercooler uses an aluminum core with plastic water tanks for OE-style fit and function. The 817653 intercooler is designed for drivers and repair shops looking for a factory-style replacement on Volkswagen Golf and Volkswagen Jetta models.

Product Details

As a Valeo OE part, the 817653 intercooler is engineered to match the original equipment application used on select Volkswagen vehicles. By reducing the temperature of air leaving the turbocharger, the charge air cooler helps the engine receive denser intake air, which supports consistent performance under load. This part is a practical choice for Volkswagen Golf and Volkswagen Jetta owners replacing a worn or damaged intercooler with an OE-style component.

This part cross-references 1J0145803L for the same application.
