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. Improves thermal efficiency by removing heat from turbocharged or supercharged air, delivering consistent power output. Enhances overall engine durability by reducing thermal stress on pistons, valves, and cylinder head components., Manufacturer: XINQQDC
