MASS AIR FLOW SENSORS
Converts the amount of air entering into the engine into voltage signals
Located directly in between air cleaner and throttle body
ECM needs to know the amount of intake air volume
Necessary to determine how much fuel to be injected inside cylinder
TURBOCHARGER
Centrifugal compressor powered by high speed turbines, driven by engine exhaust
Improves volumetric efficiency of the engines.
The function of turbocharger is to increase the amount of air entering the engine.
The power and the torque increases tremendously compared to an engine without a turbocharger
INTERCOOLERS
Mechanical device used to cool fluid including liquid and gases
Increase efficiency of the induction system by reducing air induction heat
Lowering of intake charge temperature eliminates the danger of predetonation
ADVANTAGES
Eco conscious
Increased efficiency
Max output with minimum fuel consumption
High torque
DISADVANTAGES
Low rpm
High cost
Space requirement
