Compressors and parts

Superchargers and parts are key components of a supercharging system, increasing engine power and efficiency by supplying additional air to the combustion chamber. Superchargers improve vehicle performance and acceleration response while also supporting combustion efficiency. At Global Parts, you'll find a wide selection of used car parts, including superchargers and parts, perfectly suited to BMW , Audi , Mercedes , Volkswagen , Mini , and other brands .

What is a compressor and how does it work in practice?

A car compressor is a mechanical device responsible for compressing a working medium – depending on the application, this may be air ( engine supercharging ) or a refrigerant (air conditioning) . In supercharging systems, the compressor is driven directly by the engine, which means immediate response to gas injection, without the lag typical of turbochargers. Examples include solutions used in models such as the BMW E46 (E46 supercharger) and Mini Cooper (Mini Cooper supercharger), where the emphasis is on smooth torque increases and high operating refinement.

Air conditioning compressor vs. supercharger compressor – key differences

Although the name is common, the air conditioning compressor and the supercharger perform completely different functions. The air conditioning compressor is responsible for compressing the refrigerant and maintaining the appropriate pressure in the HVAC system. It is found in models such as the BMW E90 ( BMW E90 air conditioning compressor ) and the BMW E60 530d ( BMW E60 530d air conditioning compressor ) . In turn, the supercharger increases the amount of air entering the engine, which directly affects power and torque – such solutions were used, among others, in the petrol engines of the BMW E39 series ( E39 supercharger ) and in selected versions of the Mini.

What functions do compressors and parts perform?

Compressors and their components play a key role in supercharging systems:

• Increased engine power – The compressor forces more air into the combustion chamber, allowing for more efficient fuel combustion.
• Improved acceleration – Thanks to faster air delivery, the engine responds more quickly to the gas pedal.
• Combustion efficiency – Better fuel-air mixing reduces fuel consumption and exhaust emissions.

The use of compressors in specific car models

In practice, the compressor's design and parameters are closely matched to the specific model and engine. For example, the Audi A6 C6's suspension compressor is responsible for height adjustment and ride comfort in the air suspension system, operating at pressures up to 16–17 bar . In contrast, the air conditioning compressors in the BMW E90 and E60 530d are designed for a capacity of 120–160 cm³ per revolution, ensuring stable cooling even at high outside temperatures.

Why is it worth taking care of compressors and parts ?

A malfunctioning compressor or its components can lead to a loss of power, increased fuel consumption, and engine problems. Typical symptoms include:

• Performance Loss – Compressor problems can cause a lack of extra power when accelerating.
• Loud noises – Damaged bearings or other components may produce unusual noises during operation.
• Increased fuel consumption – A faulty compressor can result in inefficient combustion.
• Check Engine Light – Charging problems may be indicated by the vehicle's diagnostic system. If you need a replacement, you'll find the right used car parts at Global Parts that will restore the full functionality of your supercharging system.

Compatibility and fit – the key to proper operation

Compressor selection is based on design compatibility with the engine or air conditioning system, as well as parameters such as displacement, clutch type, and mounting method. In modern vehicles, VIN identification is increasingly common, allowing for precise compatibility with other components, such as the air conditioning condenser, dryer, or expansion valve. This approach facilitates the construction of a coherent system and promotes internal linking between related component categories.

How to choose the right compressors and parts ?

When selecting compressors and parts, there are several key aspects to consider:

• Vehicle-specific fit – Every supercharging system has its own specific technical requirements. At Global Parts, you'll find compressors and parts perfectly suited to BMW , Audi , Mercedes , Volkswagen , Mini , and more .
• Technical condition – Used compressors and parts should be free from mechanical damage and fully functional.
• Supercharger Compatibility – Make sure the compressor you choose works with your vehicle's fuel and intake system.

Comparison table – compressor types and their applications

Compressor type	Application	Sample models	Operating range / parameters
Supercharger compressor	Increasing the amount of air in the engine	BMW E46, BMW E39, Mini Cooper	Constant boost, immediate response to gas
Air conditioning compressor	Refrigerant compression	BMW E90, BMW E60 530d	Capacity approx. 120–160 cm³/revolution
Air suspension compressor	Height and ride comfort adjustment	Audi A6 C6	Working pressure up to approx. 16–17 bar

Why choose used compressors and parts ?

Used car parts , such as used compressors and parts , is an economical solution that allows you to save money while maintaining high quality. By choosing used supercharging system components, you gain:

• Lower costs – Used compressors and parts are much cheaper than new ones, but offer just as high quality.
• Ecology – Recycling parts supports environmental protection and reduces waste.
• A wide range of products – In our store you will find used compressors and parts for the most popular car brands.

Most searched configurations and models

Phrases like BMW E46 compressor, BMW E90 air conditioning compressor, BMW E60 530d air conditioning compressor, and Audi A6 C6 suspension compressor are particularly popular among users. This is due to the large number of these models on the market and the wide availability of compatible components, which allows for optimizing operating costs without sacrificing comfort and performance.

How to take care of compressors and parts ?

To ensure that compressors and parts function reliably for a long time, it is worth following a few rules:

• Regular inspections – Check the condition of the compressor and its components during periodic technical inspections.
• Use high-quality oils and filters – Proper maintenance of the lubrication and intake systems supports the durability of the compressor.
• Avoid overloading – Prolonged high-speed driving can increase compressor wear. If you need a replacement, Global Parts has the right used car parts to ensure the performance and reliability of your supercharger system.
