Fit For Cayenne E3 Turbocharged Cooler PAB145804A PAB145803A PAB14580320 PAB14580420 4M0145804BR 4M0145803BP. OEM:PAB145804A PAB145803A PAB14580320 PAB14580420 4M0145804BR 4M0145803BP. 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. This intercooler efficiently lowers the temperature of compressed air from the turbocharger, increasing its density for more powerful and complete combustion in the engine. Its high-performance core design maximizes heat exchange area, allowing for rapid cooling of intake air and reducing the risk of engine knocking., Manufacturer: PUAYWMOZ
