The size of the collection tank is approximately 15 cm (height) x 8 cm (diameter). Cusco collection tanks are used to reduce the flow of oil vapor into the inlet. The oil vapour pollutes the intake by mixing it with the air and fuel used for combustion in the engine. Because of this pollution, in both naturally aspirated and turbocharged vehicles, it reduces combustion efficiency and increases knock risk and power factor. In addition to reducing the amount of oil vapor entering the air. The sump allows the turbocharged vehicle to add about 3psi of extra pressure without causing an explosion hazard. It is easy to install, but the bracket may need to be modified to fit the application
