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. By dissipating heat from the intake manifold before the intake air reaches the cylinder, this part notably lessens the strain on the engine's main cooling system., Manufacturer: HUASRCFP
