2002 Buick Rendezvous - Intercooler
Intercoolers are designed to cool the compressed air generated by the turbocharger or supercharger to reduce its temperature and condense the air before it is sent to the intake. This ensures the most oxygen-rich air for combustion, increasing performance and efficiency. Intercoolers are typically mounted behind the grille to utilize incoming air while driving to dissipate heat from the air supply.
