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. Water-cooled configurations provide consistent cooling effectiveness that doesn't rely on vehicle speed, ideal for regular travel within urban environments. Air-cooled systems have a simple structural layout and straightforward maintenance, appropriate for driving scenarios that often include high-speed operation., Manufacturer: XKBUAPM
