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 units boast a simple structural design and easy maintenance, fitting for situations where vehicles often operate at high speeds. Water-cooled configurations provide steady cooling that isn't affected by vehicle speed, ideal for regular commuting in urban areas., Manufacturer: AKPOUYC
