Intercooler: Refrigerators used in car engines equipped with a turbo. They take the hot air coming from the turbo and reduce its temperature before it reaches the engine intake.
Wastegates: Escape valves that open as soon as the turbine exceeds a certain pressure of exhaust gases. They bypass the exhaust gases from the turbine blades, thus reducing its rotational speed.
Sprint Boosters: They are inserted between the gas pedal and the central unit of the car (ECU) and improve the response of the gas in cars equipped with an electronic gas management system.
