- Porsche 928 4.5L 1978-82
Air Conditioning Condenser Fan Bonded Rubber Buffer
Sold each - 2 required per car
High-quality bonded rubber-metal buffer designed for
mounting the air conditioning condenser fan blower guard grille on Porsche 928
models, including early 1978–1979 variants.
Fits:
Porsche 928 4.5L 1978-79
This OEM-style rubber-metal mounting bush provides secure attachment of the condenser fan assembly while effectively absorbing vibration and reducing operational noise. It ensures the blower guard grille and fan components remain correctly aligned during operation.
Manufactured using a durable rubber-metal bonded construction, this component is engineered to withstand engine bay temperatures, vibration, and long-term mechanical stress while maintaining flexibility and structural integrity.
A direct replacement part, this condenser fan mounting buffer is essential for maintaining stable AC system operation and preventing component wear.
Key Features
• Direct replacement bonded rubber-metal buffer
• Suitable for Porsche 928 (including 1978–1979 models)
• Designed for AC condenser fan blower grille mounting
• Reduces vibration and operational noise
• Durable rubber-metal bonded construction
• OEM-style fit and function
Function and Purpose
This rubber buffer acts as a mounting support and vibration isolator for the air conditioning condenser fan assembly.
It helps to:
• Secure the condenser fan and blower grille assembly
• Reduce vibration transfer within the AC system
• Minimise noise during fan operation
• Protect surrounding components from stress and wear
Why Replace Your AC Condenser Fan Buffer
Over time, rubber-metal mounts degrade due to heat, vibration, and age.
Common issues include:
• Cracked or hardened rubber
• Reduced vibration damping performance
• Loose or unstable fan assembly
• Increased noise during AC operation
Replacing the buffer restores proper mounting stability and ensures efficient AC system performance.

OEMatch Fans & cowlings — Fit, Function, Confidence
Designed for Porsche models, these fans and cowlings restore directed airflow through the radiator and A/C condenser to help control engine and refrigerant temperatures and reduce heat build-up during low-speed running. Many owners search for genuine or OEM fans & cowlings; these are direct-fit alternatives designed to match the original form, fit and function.
Available Types
- Electric radiator fan assemblies
- Fan cowling and shroud panels
- Replacement fan motors and single blades
- Complete fan packs with mounting hardware
Understanding OEMatch Fans & cowlings
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original fans & cowlings.
OE (Original Equipment) refers to parts matching original specifications for the fans & cowlings and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM fans & cowlings engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Fans circulate air through the radiator and condenser while the cowling channels that flow to where it is needed most. OEMatch focuses on parts for Porsche applications, cataloguing an extensive range of part references and components to support repairs and restorations across multiple Porsche generations.
Benefits Include
- Restores effective cooling and supports stable engine temperatures
- Improves A/C condenser airflow for consistent cabin cooling
- Reduces noise and vibration through correct mounting and balance
- Sustains thermal management during slow-speed or high-load driving
Why Fans & Cowlings Wear and Fail
- Fan motor bearings can seize or wear after prolonged service
- Impact or debris can crack blades or the cowling, disturbing airflow
- Corrosion and electrical connector degradation reduce reliability
- Heat cycles and vibration cause material fatigue and distortion
The Importance of Replacing with OEMatch Fans & cowlings
Replacing worn or damaged fans and cowlings maintains efficient heat exchange and protects critical engine and A/C components. Correctly matched replacements restore directed airflow, lower the risk of overheating and preserve cabin cooling performance for Porsche models. Choosing appropriately specified parts also helps reduce recurring faults caused by misalignment or incorrect mounting.
Advantages
- Designed to fit original mounting points and clearances
- Constructed from heat-resistant materials suited to under-bonnet environments
- Offered in complete assemblies to simplify replacement and refit
