Fit For Cooper S R56 R57 Engine 1.6L Turbo 2007-2012 Silver/Black Front Mounting Intercooler. 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. The presence of an intercooler effectively prevents engine knocking or detonation, which safeguards critical internal components from potential damage under high boost. 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
