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. Air-cooled models have a simple build and are easy to maintain, appropriate for driving scenarios that frequently involve high speeds. Water-cooled systems offer reliable cooling efficiency that stays consistent no matter the vehicle's speed, suitable for daily commuting in cities., Manufacturer: QIUYMGFG
