Fit For SWM G01 G05 1119100-D02 1119100-D03 Intercooler Assembly. OEM NO. : 1119100-D02 1119100-D03. By significantly lowering the temperature of air compressed by the turbocharger, the intercooler increases its density, allowing more oxygen to enter the cylinders for combustion. Lightweight aluminum construction reduces vehicle weight, further enhancing fuel economy and dynamic performance. Precision-engineered fin and tube structures maximize heat exchange area while minimizing airflow resistance and pressure loss., Manufacturer: KNZVUUY
