Comprehensive offer of used intake and fuel system parts – air filters, throttles, fuel pumps, injectors, and intake manifolds
What components make up the intake and fuel system?
Have you ever wondered what determines the performance and efficiency of your engine? The intake and fuel systems play a key role in ensuring the proper mixing of air and fuel, which translates into power, economy and ecology. In the Global Parts automotive store you will find a wide range of used car parts , such as air filters, **throttle valves , fuel pumps and fuel injectors . We offer parts for intake and fuel systems for BMW , Audi, Volkswagen , Mercedes and Mini, adapted to various models and needs.
How does the intake and fuel system work?
The intake and fuel systems are systems that work together to deliver a mixture of air and fuel to the combustion chamber. Each component of this system has a specific task:
- Fuel Pumps and Level Sensors – They are responsible for the correct supply of fuel to the engine and controlling its amount in the tank.
- Fuel tanks and filler pipes – They store fuel and allow it to be refueled safely.
- Air and fuel intake sensors – They monitor the amount of air and fuel supplied, optimizing engine operation.
- Throttles – Regulate air flow to the engine, affecting its performance and response to the gas pedal.
- Vacuum pumps – They support the operation of vacuum systems such as brakes and control valves.
- Air filters – They protect the engine against contamination by ensuring clean air in the combustion process.
- Fuel filters – Removes contaminants from fuel, protecting the injection system and fuel pump.
- Intake manifolds – Distributes air evenly into the cylinders, increasing combustion efficiency.
- Air filter housings – Protect air filters from damage and ensure their optimal operation.
- Cables, hoses and pipes – They transport fuel and air between individual system elements.
- Turbochargers, compressors and coolers – They increase the amount of air supplied to the engine, improving its performance.
