Air Filter Housing Rubber Hose.

The OE MATCH Air Filter Housing Rubber Hose 91110827200/1 is a replacement rubber connection hose designed for selected classic Porsche 911 models manufactured between 1972 and 1977.

Fits:

• Porsche 911 1972-77 Carburettor Cars (Mechanical Injection Only)

Diagram Ref No 14

Designed to provide OE-style fitment and functionality, this component forms part of the original air cleaner and mechanical fuel injection intake arrangement.

The hose connects the air filter housing snorkel to the associated regulator housing, helping maintain the intended airflow connection between these components.

Also known as an air cleaner snorkel hose, air filter housing connection hose or intake regulator hose, this flexible rubber component accommodates the connection between the adjoining intake system parts.

The Porsche 911 air cleaner system is designed to supply filtered air while maintaining the correct configuration of the engine's intake and associated control components.

Over time, original rubber hoses can deteriorate due to engine heat, temperature changes, vibration, exposure to oil vapours and general ageing.

A damaged or poorly fitted hose may become cracked, hardened, split or loose, potentially allowing unwanted air movement and compromising the original intake arrangement.

The OE MATCH replacement provides a practical solution for restoring the original hose connection without replacing the complete air cleaner housing.

Ideal for engine bay refurbishment, air intake repairs, mechanical fuel injection system maintenance and classic Porsche restoration projects, this component helps preserve the factory-style configuration of the air cleaner assembly.

What This Product Does:
The air filter housing rubber hose forms a flexible connection between the air cleaner snorkel and the associated regulator housing on applicable Porsche 911 intake systems.

Its key functions include:

• Air Cleaner Connection: Connects the air filter housing snorkel to the associated regulator housing.
• Airflow Routing: Helps maintain the intended passage between the connected air cleaner components.
• Secure Component Connection: Provides a flexible interface between adjoining intake system parts.
• Air Leakage Reduction: Helps maintain a secure connection when correctly fitted and clamped.
• Intake System Integrity: Supports the original air cleaner and regulator housing arrangement.
• Vibration Accommodation: Allows limited flexibility between connected components during normal engine operation.
• Temperature Resistance: Designed for the conditions encountered within the engine compartment.
• Original Equipment Configuration: Maintains the factory-style hose routing and connection arrangement.
• Restoration Compatibility: Provides an OE-style replacement for deteriorated original rubber hoses.
• Air Cleaner System Maintenance: Allows the connecting hose to be renewed independently of the complete air cleaner assembly.

Symptoms Of Wear Or Failure:
The air filter housing rubber hose is exposed to repeated temperature changes, vibration and environmental ageing throughout the vehicle's service life.

Common symptoms include:

1. Cracked or Split Rubber

Visible cracks or splits may develop as the rubber loses flexibility.

These can compromise the connection between the air cleaner snorkel and regulator housing.

2. Hardened or Brittle Hose

Prolonged engine heat and ageing can cause the rubber to become stiff, brittle or less capable of sealing around the adjoining components.

3. Loose Hose Connections

A deteriorated or incorrectly fitted hose may become loose at one or both ends.

This can affect the intended airflow arrangement and may produce unwanted movement.

4. Shrunken or Deformed Rubber

Ageing may cause the hose to shrink, distort or lose its original shape, making correct installation difficult.

5. Torn Hose Ends

Repeated removal, overtightened clamps or general deterioration may cause the ends of the hose to split or tear.

6. Air Leakage Around Connections

A damaged hose or loose clamp may allow air to escape from or enter the connected passage.

The effect on engine operation depends on the hose's function within the specific intake configuration.

7. Increased Intake Noise

Unexpected hissing, whistling or changes in intake sound may indicate a loose or damaged connection.

8. Oil Residue and Surface Deterioration

Exposure to engine oil vapours and contamination may contribute to softening, swelling or deterioration of some ageing rubber components.

9. Visible Hose Collapse

A weakened or incorrectly installed hose may become distorted or collapse, potentially affecting the intended airflow passage.

10. Damaged Hose Clamps

Corroded, loose or overtightened clamps may prevent the hose from being secured correctly.

11. Engine Running Irregularities

Depending on the specific intake arrangement, significant air leaks or restrictions may contribute to inconsistent engine behaviour.

However, poor running should not automatically be attributed to this hose.

12. Deterioration Identified During Servicing

Cracks, hardening or damaged hose ends may become apparent when removing the air cleaner assembly for maintenance.

Why Replacement Matters:

• Replacing a cracked, hardened or damaged air filter housing rubber hose helps maintain the original intake system configuration and supports reliable operation of the associated air cleaner components.
• The Porsche 911 air cleaner assembly is designed to route air through the appropriate components while maintaining secure connections.
• The rubber connection hose provides an important interface between the air cleaner snorkel and regulator housing.
• When this hose deteriorates, the original connection may no longer remain securely sealed or correctly positioned.

This OE Match clutch vacuum control hose connects the intake manifold to the control valve in the Sportomatic clutch-release system. It provides the vacuum connection needed by the clutch control assembly on the applications listed below.

Fits

• Porsche 911 1967–1968 w/ Sportomatic transmission
• Porsche 911 1969–1972 Sportomatic
• Porsche 914 1970–1971 with Sportomatic transmission
  
  Check fitment for your specific vehicle (model, year, engine) before ordering.
  
  Diagram ref no 14
  
  What Is This Part?

This is the hose linking the engine intake manifold to the Sportomatic control valve. Sportomatic uses a vacuum-operated clutch-release arrangement, with the control valve regulating vacuum to the clutch servo. This hose forms part of the vacuum supply path, so its condition and the sealing of its connections matter to correct operation. During repairs, it should be checked alongside the other vacuum hoses, reservoir, valve and servo rather than treated as the only possible source of a clutch-release fault.

What Does This Part Do?

• Connects the vacuum supply: Links the intake manifold to the Sportomatic control valve.
• Maintains a sealed passage: An intact hose and correctly seated connections help prevent air entering this part of the vacuum circuit.
• Supports clutch-release control: Supplies the vacuum connection used by the valve within the clutch operating system.
  
  Why Replace This Part?

Replace the hose if inspection finds splits, deterioration or connections that no longer seal securely. A leak can reduce the vacuum available to the clutch-release system, while a flattened or kinked hose can restrict the passage. Replacing a confirmed defective hose addresses that fault without assuming that the control valve or clutch itself also needs renewal.

If the clutch does not disengage properly, inspect the complete operating system. Vacuum leaks, servo faults, linkage adjustment and electrical control problems can produce overlapping symptoms, so diagnosis should come before replacing further components.

When to Replace This Part?

• Visible damage: Cracks, splits, abrasion or damaged hose ends are present.
• Poor connection: The hose no longer seats securely on its connection points.
• Restricted passage: The hose is kinked, crimped or flattened.
• Confirmed leakage: Testing identifies a vacuum leak through the hose or its ends.
• Removal and refitting: Inspection during manifold or Sportomatic work reveals deterioration that prevents sound refitting.
  
  Where Is This Part Fitted?

Location: Between the engine intake manifold and the Sportomatic control valve, within the clutch-release vacuum system. Check the existing routing and adjoining connections when fitting the replacement.

Product Summary

• Product: Clutch vacuum control hose.
• Brand: OE Match.
• Connection: Intake manifold to Sportomatic control valve.
• Purpose: Provides the vacuum connection used by the clutch-release control system.

Diagram ref no 16

The hose channels warm air from the heat exchanger into the air intake system, helping the engine reach optimal operating conditions more quickly. This improves fuel vaporisation and engine efficiency during cold running.

Without proper airflow through this hose, cold start performance and drivability may be affected.

Function
•  Transfers warm air from heat exchanger to air filter housing
•  Supports cold start performance and engine warm-up
•  Improves fuel vaporisation in carburettor/injection systems
•  Maintains correct airflow within intake system

Over time, hot air hoses can become brittle, cracked, or collapsed due to heat and age. This can reduce airflow efficiency and impact engine performance, especially during cold starts.

Replacing the hose restores proper airflow, improves engine efficiency, and helps maintain the correct operation of the intake system - particularly important for classic carburetted engines.

When to replace
•  Cracked, brittle, or split hose
•  Collapsed or restricted airflow
•  Poor cold start performance
•  Missing or disconnected ducting
•  During engine bay restoration or service
