BMW E81 E87 E90 E91 E92 Radiator AC Rad Condenser Petrol 6930040

Description

BMW E81 E87 E90 E91 E92 Radiator AC Rad Condenser is an original air conditioning system component designed for BMW vehicles with petrol engines. As part of the Condensers (radiators) group, it is responsible for effectively dissipating heat from the refrigerant, which translates into a stable, comfortable cabin temperature. This used OEM component is a sensible choice for drivers looking for a technically compatible solution at an attractive price.

Function and role of the condenser in the air conditioning system

The air conditioning condenser in the BMW E81, E87, and E90 series operates in the high-temperature part of the refrigerant circuit, where compressed gas releases heat into the surroundings. A correctly selected component ensures:

• stable pressure in the air conditioning system,
• efficient heat dissipation from the refrigerant,
• effective cabin cooling even under high thermal load,
• reduced strain on the air conditioning compressor and other components.

Thanks to the proper OEM design, the condenser works with the factory fan, hoses, and accessories, which limits the risk of leaks and installation problems.

Compatibility with petrol engines

The presented condenser is intended for BMW vehicles powered by petrol, which is important when selecting cooling and air conditioning system components. Using the correct variant for a given fuel type:

• facilitates proper fitment to the factory engine accessories,
• ensures compliance with the original front-end architecture,
• minimizes the risk of collision with other components (coolant radiator, intercooler, reinforcements).

For workshops and individual users, this means simpler part selection and a lower risk of needing installation modifications.

Characteristics of the used OEM component

The BMW air conditioning condenser in this offer is an original OEM component in used condition. In practice, this means:

• factory fitment for BMW E81, E87, E90 models with air conditioning,
• preservation of the original geometry of connections and mounts,
• possibility of installation in place of a worn or damaged condenser without interfering with the car’s structure.

A used OEM element is often chosen as a technically safe alternative to cheaper replacements of uncertain manufacturing quality.

Benefits of using an original BMW condenser

Replacing a worn condenser with an original BMW component in the air conditioning system brings a number of practical benefits:

• Stable cooling performance – proper heat dissipation from the refrigerant translates into faster interior cooling.
• Better cooperation with other components – the compressor, expansion valve, and receiver-drier operate under conditions close to factory specifications.
• Reduced risk of leaks – proper fitment of ports and mounts facilitates correct installation of air conditioning lines.
• Possibility of maintaining the original front-end configuration without additional modifications.

For cars driven daily, this means more predictable air conditioning operation and a lower risk of costly failures resulting from system overload.

Selection, installation, and additional information

Before purchasing, it is worth verifying the condenser’s compatibility with the specific equipment version and model year of your BMW by using OEM markings and interchangeable numbers available in the technical specification. This facilitates precise part matching for a given vehicle and reduces the risk of ordering errors.

If you are planning a comprehensive repair or upgrade of the front air conditioning zone in your BMW and need other elements from the same group, such as additional condensers, AC radiators, or related cooling modules, check the available parts in the BMW Condensers (radiators) category.
