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. Supports higher boost pressures by keeping intake air temperatures within an optimal operating range. Reduces exhaust gas temperature by cooling the air-fuel mixture before the combustion event., Manufacturer: AWEUDNHI
