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. This intercooler efficiently lowers the temperature of compressed air from the turbocharger, increasing its density for more powerful and complete combustion in the engine. Its high-performance core design maximizes heat exchange area, allowing for rapid cooling of intake air and reducing the risk of engine knocking., Manufacturer: PUAYWMOZ
