Silicone sleeve set for GT3 intake manifold. Porsche 964 / 993 / 996
Sold as a set of 6
Fits:
Porsche 964 - 1989 to 1994 (with GT3 inlet upgrade)
Porsche 993 - 1994 to 1998 (with GT3 inlet upgrade)

The original rubber couplers for Porsche 996 and 997 GT3 models have become increasingly costly and hard to source, and many enthusiasts opt to avoid them for high-performance applications like hot rods or track cars due to their limited heat resistance.
Our precision-molded OEM+ silicone sleeves are the perfect direct replacement, offering double the temperature resistance of the original rubber couplers along with an enhanced appearance. These high-quality sleeves are essential for replacing worn-out rubber parts and are ideal for air-cooled hot rods undergoing a modern DBW (Drive-By-Wire) conversion using a GT3 intake plenum.
This set includes six (6) silicone sleeves

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.
