S Cross Intercooler

When air is drawn into the turbocharger, boosted, and then forced into the engine, it gets very hot. And hot air isn't as good for an engine as cool air. Therefore many turbocharged engines make use of an intercooler.An intercooler is basically an air-to-air radiator. The hot air from the turbo enters at one end, and as cooled as it passes through the intercooler (much like the water in a car's radiator) before entering the engine at a much lower temperature.This allows the engine to make full use of a simple principal of physics; cooler air is more dense than hotter air.This basically means that for a given volume (of our engine's cylinder for example) we can get more oxygen into the same space when the air is denser – and more oxygen means better performance.
