The air duct channels cooling air directly to the oil cooler, ensuring efficient heat dissipation from engine oil. This helps maintain stable oil temperatures and prevents overheating in air-cooled engines. Proper airflow management is critical for consistent engine performance and longevity.
Function
• Directs cooling air to the oil cooler
• Improves heat dissipation from engine oil
• Supports stable engine operating temperatures
• Ensures efficient airflow within engine tinware system
Over time, air ducts can crack, warp, or go missing during engine work. A damaged or missing duct reduces airflow to the oil cooler, leading to higher oil temperatures and potential engine wear. Replacing this component ensures proper cooling airflow, protects engine components, and maintains optimal performance - especially important for air-cooled engines.
When to replace:
• Cracked, broken, or missing duct
• Overheating or high oil temperatures
• During engine rebuild or restoration
• Poor airflow or incorrect engine tinware setup
• Preventative maintenance on classic vehicles

This OE Match strap secures the alternator cooling fan or impeller housing to the engine block or accessory mount, maintaining correct belt alignment, reducing vibration, and preserving the designed airflow path for the cooling system. Its robust stainless construction helps ensure that cooling performance and accessory alignment remain stable through many heating/cooling cycles and varying environmental conditions.
Installed between the fan housing and the engine accessory bracket, the stainless steel strap:
• Provides a rigid mounting point for the alternator fan/impeller housing
• Maintains accurate belt and pulley alignment
• Reduces the risk of strap deformation, corrosion, or fatigue
• Helps ensure consistent airflow distribution for engine cooling
The factory strap is steel and, over time, can be prone to corrosion, bending, fatigue, or surface degradation due to heat cycling and environmental exposure. These issues can lead to fan misalignment, belt wear, and reduced cooling performance. Upgrading to an OE Match stainless steel strap enhances reliability, resists corrosion, and improves longevity - ideal for engines used in daily driving, classic car tours, or restoration builds where long-term durability is important.
When to replace:
• Original strap shows corrosion, rust, or fatigue cracks
• Fan housing shows signs of misalignment or vibration
• During alternator, cooling fan, or accessory belt service
• When restoring or rebuilding the engine assembly
• Preventive upgrade to improve reliability

- Porsche 911 1987-1989 3.2L G50
- Porsche 911 1978-1989 3.3L Turbo (930)
Manufactured from high-quality cast aluminium alloy, the housing offers excellent structural rigidity, corrosion resistance and heat dissipation. Precision-machined mounting points ensure accurate alignment of the alternator and cooling fan, providing proper belt tracking and optimum airflow throughout the engine cooling system. It is ideal for restoration projects or replacing cracked, corroded or damaged original fan housings.
What This Product Does:
- Supports and positions the alternator and engine cooling fan.
- Directs cooling airflow over the engine cylinders and cylinder heads.
- Maintains correct fan and alternator alignment.
- Ensures proper drive belt tracking.
- Helps maximise engine cooling efficiency.
- Provides secure mounting for associated engine components.
- Restores the original appearance of the engine compartment.
- Forms an essential part of the air-cooled engine cooling system.
Symptoms Of Wear Or Failure:
- Cracks or fractures in the housing.
- Corrosion or oxidisation of the alloy.
- Misaligned cooling fan or alternator.
- Excessive fan belt wear or belt misalignment.
- Fan rubbing against the housing.
- Increased engine operating temperatures.
- Unusual noises from the fan assembly.
- Loose mounting points or damaged fixing threads.
- Visible impact damage.
- Poor engine bay appearance during restoration.
Why Replacement Matters:
- The alternator fan housing is exposed to constant engine vibration, high operating temperatures and repeated thermal expansion and contraction. Over time, the alloy housing can develop cracks, corrosion or damaged mounting points, affecting the alignment and efficiency of the engine cooling fan and alternator.
- A damaged fan housing can reduce cooling airflow, increase fan belt wear and place additional strain on the alternator and cooling fan assembly. In air-cooled Porsche engines, reduced cooling efficiency can contribute to elevated engine temperatures, which may affect reliability and long-term engine durability.
- Replacing a worn or damaged alternator fan housing restores the correct positioning of the cooling fan and alternator, ensuring efficient engine cooling and reliable accessory drive operation. The OE Match replacement provides factory-style fitment, high-quality cast alloy construction and exceptional durability, helping preserve the performance, reliability and authentic appearance of your Porsche.

OEMatch Air cooling parts — Fit, Function, Confidence
Air cooling parts manage airflow and operating temperature in Porsche engines. OEMatch supplies a broad selection of fan assemblies, shrouds, ducts, pulleys and cooling tins selected for Porsche applications to support maintenance, restoration and routine servicing.
Available Types
- Fan assemblies and driven fans
- Shrouds, ducts and cooling tins
- Pulleys, belts and drive hardware
- Housings, mounts and fasteners
Understanding OEMatch Air cooling parts
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original air cooling parts. OE (Original Equipment) refers to parts matching original specifications for the air cooling parts and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM air cooling parts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Air cooling components direct airflow across cylinders, heads and oil passages to control temperatures, prevent hotspots and support combustion stability. Correct ducts and shrouds reduce localised overheating and help maintain oil and engine life; fans and pulleys control airflow volume and speed across the full rev range.
Benefits Include
- Restored and controlled airflow across critical engine areas
- More consistent operating temperatures under varied loads
- Reduced risk of overheating-related damage
Why Air cooling parts Wear and Fail
- Thermal stress causing cracks, warping or deformation
- Corrosion and debris damage to fan blades, ducts or fasteners
- Vibration and material fatigue leading to loosened mounts or imbalance
The Importance of Replacing with OEMatch Air cooling parts
Replacing worn or damaged air cooling parts helps maintain reliable airflow and stable engine temperatures on Porsche models. Correct parts reduce the chance of heat-related faults, support predictable running and protect more costly components from secondary damage. Choosing parts made to the correct dimensions and fitment aids straightforward installation and long-term dependability.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances
- Designed to fit original mounting points and clearances where applicable
- A broad selection to suit restoration, maintenance and model-specific needs
Support & Advice
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified.
