- 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.

This gasket is for the fan housing (blower casing) and cover interface on classic Porsche 356 (B/C) and Porsche 912 models. The spacer ring ensures proper clearance, sealing and alignment between the main fan housing and the cover plate. Manufactured to replicate the original Porsche part in size and thickness.
Fits:
Porsche 912 1965 - 1969
Porsche 356 B / C 1960 - 1965

• Position on Vehicle: Engine bay – between fan housing (blower shroud) and fan cover / generator mounting to body or engine casing.
• Function: Maintains correct spacing, alignment and sealing of the fan housing, ensuring air-flows correctly through the engine’s cooling blower system, helping preserve engine temperature regulation and reduce vibration or mis-alignment.
Even though small, the spacer ring plays a crucial role in the cooling system geometry. If the original spacer is missing, crushed, incorrect thickness or degraded, you may experience:
• Mis-aligned fan housing or blower which can lead to inefficient airflow or overheating
• Vibration, noise or abnormal fan behaviour due to improper clearance
• Premature wear of fan shroud, generator or other components if clearance is incorrect
• Difficulty achieving correct engine temperature control or unstable idle-temperature behaviour.
Replacing with this spacer ensures the fan housing retains correct alignment, airflow is maintained as designed and cooling performance remains reliable.
