Replacement Impeller blade fan centre support complete with rivets.
This impeller blade fan centre support is a high-quality replacement centre hub support for the engine cooling fan (alternator/generator impeller) on early Porsche 911 models.

Fit:
Porsche 911/912 (1965-1969) (911 up Through 68)
Porsche 911T/E/S Carrera RS (1970 - 1973)
Porsche 911/911S / Carrera (1974 - 1977)

The fan centre support forms the core mounting structure for the cooling fan (impeller) that attaches to the alternator / generator shaft. It ensures the cooling fan is securely aligned and balanced, allowing it to draw air through the engine compartment and over the engine’s cylinder heads and oil cooler - helping regulate operating temperatures and prevent overheating.

On classic air-cooled 911 engines, the cooling fan is critical to drawing fresh air through the engine bay and sustaining proper temperatures. The centre support (hub) is the backbone of the fan assembly - if it’s worn, corroded, or damaged:
• The fan can wobble or run out of balance
•  Bearing loads on the alternator/generator can increase
•  Cooling airflow can diminish
•  Noise and vibration can increase.

Replacing an old or deteriorated centre support with an OE Match unit restores precise fan alignment, improves cooling efficiency, and helps protect surrounding engine components from heat-related wear.

When to replace. Replace the fan centre support if you notice any of the following:
•   Excessive fan wobble or vibration
•   Noisy operation from the fan or alternator area
•   Visible corrosion or wear on the old hub
•   During overhaul of the fan, generator/alternator, or cooling system

SET OF 2

Fits:
Porsche 911 F model T/E/S 1970-73
Porsche 914/6
Porsche 930 turbo 3.0/3.3 ('75-'89)
Porsche 911 2.7 S/SC ('74-'77)

This is a replacement set for Porsche parts numbers:
   •    Left side: 91110632700
   •    Right side: 90110632102 , 90110603101, 90110602150, 93016032102.

Set of two OE Match engine fan housing air outlet shrouds, designed as direct-fit replacements for the original Porsche fan outlet ducting on air-cooled engine models. These shrouds direct cooling air from the engine fan toward the cylinder heads and accessories, ensuring optimum engine temperature control and airflow management.

The fan housing air outlet shrouds channel warm airflow from the engine cooling fan, directing it efficiently around the engine’s critical hot spots. By shaping and focusing the fan’s output, these shrouds help maintain even and effective cooling, which is vital for controlling cylinder head and oil temperatures, especially under spirited driving conditions.

On air-cooled Porsche engines, effective airflow is critical to maintaining acceptable operating temperatures. Over time, original fan shrouds and outlets can crack, warp, or deteriorate, leading to air leaks, reduced cooling performance, and elevated cylinder head/oil temperatures. These conditions increase wear on internal components and can lead to performance losses or mechanical issues. Replacing damaged or missing shrouds with an OE Match set restores proper airflow paths, ensuring the fan’s air is directed where it’s needed most, and helps preserve engine health, reliability, and coolant-free performance.

When to replace:
•  Original shrouds are cracked, warped, or missing
•  During engine rebuild or cooling system service
•  When upgrading other cooling components (e.g., fans, housings)
•  If overheating or uneven temperature issues are detected
•  Preventive replacement on high-mile engines

Aluminium Engine Baffle Kit – 8 Piece 

Restore the efficiency of your air-cooled engine with this Aluminium Engine Baffle Kit, comprising 8 precision-manufactured aluminium baffle plates. This complete kit helps ensure cooling air is directed exactly where Porsche intended, protecting your engine from excessive operating temperatures.

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
• Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera

Unlike a water-cooled engine, the classic Porsche flat-six relies entirely on carefully managed airflow generated by the engine cooling fan. The aluminium baffle plates fit between the cylinders and cylinder heads, sealing critical gaps and directing cooling air through the cooling fins rather than allowing it to escape around the engine.

Without these baffles in place, cooling efficiency is significantly reduced, allowing hot spots to develop around the cylinders and heads. This can lead to increased engine temperatures, reduced reliability and accelerated engine wear.

Manufactured to OE Match standards from lightweight, corrosion-resistant aluminium, this 8-piece kit offers factory-style fitment and is an essential component during engine rebuilds, restorations or whenever the engine is stripped for maintenance.

What Do Engine Baffle Plates Do?

Engine baffle plates are a critical part of the Porsche air-cooled engine's cooling system. Installed between the cylinders and beneath the cylinder heads, they ensure the airflow produced by the cooling fan is forced through the cylinder and head cooling fins.

Their primary functions include:

• Directing cooling air through the cylinders and heads
• Preventing cooling air from escaping through unwanted gaps
• Promoting even engine temperatures
• Reducing the risk of localised overheating
• Improving cooling efficiency throughout the engine

Although hidden once the engine is assembled, these small aluminium panels play a vital role in maintaining the longevity and performance of the flat-six engine.

Why Do Engine Baffles Fail?

Over many decades of service, engine baffles are exposed to continual heat cycles, vibration, corrosion and repeated engine dismantling.

Common causes of failure include:

• Corrosion caused by moisture and oxidation
• Distortion from excessive heat
• Cracking due to vibration or incorrect handling
• Damage during engine disassembly
• Missing panels following previous engine repairs
• Incorrectly fitted replacements

Bent or damaged baffles may no longer seal correctly against the cylinders, allowing valuable cooling air to bypass the cooling fins. Even small gaps can reduce the effectiveness of the air-cooling system.

When Should Engine Baffles Be Replaced?

Because these components are only accessible during engine disassembly, replacement is highly recommended whenever the engine is apart.

Replacement should be considered if:

• The engine is being rebuilt
• Cylinder heads or barrels are removed
• Baffles show corrosion or oxidation
• Panels are bent or distorted
• Cracks are visible
• One or more baffles are missing
• Previous repairs have used damaged or incorrect parts

Installing new OE Match aluminium baffles during an engine rebuild helps restore the original cooling efficiency and contributes to the long-term reliability of the engine.

Porsche 911 Engine Cooling & Air-Cooled Engine Components

Efficient cooling is fundamental to the performance and longevity of every classic air-cooled Porsche engine. Unlike water-cooled engines, the Porsche flat-six depends entirely on carefully controlled airflow to dissipate heat from the cylinders and cylinder heads.

Every component within the cooling system—including the engine fan, fan housing, engine tinware and internal aluminium baffles—works together to ensure cooling air is distributed evenly throughout the engine.

Replacing worn or missing baffles during an engine rebuild helps restore the factory cooling system to its original efficiency, reducing the risk of overheating and contributing to longer engine life.

Whether you're completing a concours restoration or a high-quality engine rebuild, correctly fitted aluminium baffles are an essential part of achieving reliable performance.

Benefits of Replacing the Engine Baffle Kit

• Restores correct cooling airflow
• Improves cylinder and cylinder head cooling
• Reduces the risk of overheating
• Replaces corroded or damaged original baffles
• Helps maximise engine reliability and longevity
• Provides factory-style fitment
• Essential for professional engine rebuilds and restorations
