What This Product Does

As coolant temperature changes, the thermostat adjusts circulation within the cooling circuit. Its operation manages warm-up and the subsequent flow needed to control engine temperature. The insert works inside the associated housing; it is not a radiator or water pump.

Functions

• Adjusts coolant circulation in response to temperature.
• Manages cooling-circuit flow while the engine warms.
• Contributes to temperature control once the engine is warm.

Technical Details

• Genuine Porsche component: 9GT121113A.
• Internal diagram descriptions identify it as a thermostat insert and thermostat.
• The 997 assembly covers M97.77 applications for 2010–11 and the M97.74 GT3 RS 4.0 for 2011.
• The additional engine-water-circuit diagram covers the 2021 911 (992) GT3 Cup.
• Surrounding housings, sealing rings and O-rings have separate diagram entries.

Symptoms of Fault

• Abnormally high or inconsistent engine temperature.
• Cooling-system warnings, steam or coolant loss.
• Dampness or dried coolant deposits near housing joints.
• Gurgling associated with air or insufficient coolant.

These signs can also arise from other cooling components, so diagnosis should establish the cause before the insert is replaced.

Why Replacement Matters

Incorrect thermostat operation can disrupt temperature control. Renewing an insert with a confirmed fault addresses that component rather than masking a wider cooling-system problem. During the repair, examine the housing and its separate seals for deterioration, and establish which additional components the job requires.

FAQs

• Does the insert include its housing?
  The supplied diagrams show distinct housing components alongside the thermostat. Do not assume those components are included.
• Are sealing components identified separately?
  Yes. O-rings and sealing rings appear as individual entries in the associated assemblies.
• What information is needed to confirm suitability?
  Use 9GT121113A together with the vehicle model, production year, engine identification and corresponding parts diagram. For the Cup application, confirm the motorsport vehicle specification.

Manufactured to Porsche's original equipment specifications, this rear suspension bump stop provides progressive cushioning when the suspension approaches the limit of its compression travel. It helps absorb excessive suspension movement caused by heavy loads, uneven road surfaces, potholes and demanding driving conditions.

Positioned within the rear shock absorber assembly, the stop buffer acts as a protective cushioning element, helping prevent harsh metal-to-metal contact and reducing excessive stress on the shock absorber and associated suspension components.

During normal driving, the rear suspension continuously compresses and rebounds to maintain comfort, stability and road contact. When the suspension experiences greater compression, the stop buffer provides additional resistance, helping reduce harsh impacts and protect critical suspension components.

Over time, the original stop buffer can deteriorate due to ageing, repeated compression, moisture, road contaminants and temperature changes. Worn or damaged buffers may lose their ability to cushion suspension movement effectively, potentially resulting in harsher suspension impacts, increased noise and additional wear on surrounding components.

Replacing a deteriorated stop buffer with a Genuine Porsche component helps restore the intended suspension cushioning, maintain driving comfort and protect the rear shock absorber assembly from excessive compression forces.

Ideal for routine suspension maintenance, shock absorber replacement and rear suspension repairs, this genuine Porsche stop buffer provides original equipment fitment and dependable performance.

What This Product Does:
The rear stop buffer, also known as a suspension bump stop or jounce bumper, performs several important functions within the vehicle's rear suspension system.

• Limits Excessive Suspension Compression: Provides progressive resistance as the rear suspension approaches the end of its available compression travel.
• Protects the Shock Absorber: Helps prevent the shock absorber from experiencing harsh mechanical impacts when the suspension compresses heavily.
• Absorbs Suspension Impacts: Cushions the effects of potholes, speed bumps, uneven roads and heavy suspension loading.
• Prevents Harsh Bottoming Out: Reduces the severity of impacts when the suspension reaches its compression limits.
• Maintains Ride Comfort: Helps reduce harsh jolts and vibrations transmitted through the vehicle during extreme suspension movement.
• Protects Suspension Components: Reduces excessive mechanical stress on the shock absorber, mounting points and surrounding suspension assemblies.
• Supports Controlled Suspension Movement: Provides additional resistance under heavy compression to help maintain predictable suspension behaviour.
• Accommodates Vehicle Loading: Helps protect the suspension when carrying passengers, luggage or heavier loads.
• Maintains Factory Suspension Performance: Designed to work with the specified Porsche rear suspension configuration.

Symptoms Of Wear Or Failure:
Rear suspension stop buffers are exposed to repeated compression, road debris, moisture and temperature changes. Over time, these conditions can cause the original material to deteriorate.

Common symptoms of a worn or damaged rear stop buffer include:

• Harsh Suspension Bottoming Out: Heavy jolts or impacts may be felt when driving over potholes, speed bumps or uneven road surfaces.
• Knocking or Thudding Noises: Unusual noises from the rear suspension may occur when the suspension compresses heavily.
• Cracked or Split Buffer: Visible cracking, splitting or deterioration of the cushioning material.
• Crumbling or Disintegrating Material: Ageing material may break apart, leaving fragments around the shock absorber assembly.
• Reduced Suspension Cushioning: The suspension may feel harsher during larger bumps or heavy compression.
• Excessive Suspension Impact: A severely deteriorated or missing buffer may allow harder impacts at the limits of suspension travel.
• Deformed or Compressed Buffer: The stop buffer may become permanently flattened or distorted, reducing its effective cushioning.
• Increased Suspension Vibration: Harsh impacts may transmit additional vibration into the vehicle body.
• Premature Shock Absorber Wear: Repeated bottoming-out events may place additional strain on the shock absorber and its mounting components.
• Visible Missing or Damaged Buffer: Inspection may reveal that the original stop buffer has become detached, broken or completely deteriorated.

Why Replacement Matters:
Replacing a worn or damaged rear suspension stop buffer helps maintain the integrity, comfort and reliability of the vehicle's suspension system.

Key Benefits of Replacement:

• Restores Suspension Cushioning: Re-establishes the protective cushioning effect during heavy suspension compression.
• Helps Prevent Harsh Bottoming Out: Reduces the severity of impacts when the suspension approaches the end of its travel.
• Protects the Rear Shock Absorbers: Helps reduce excessive mechanical stress that may contribute to premature shock absorber damage.
• Maintains Driving Comfort: Minimises harsh jolts and impacts transmitted through the vehicle.
• Reduces Suspension Noise: Helps prevent impact-related knocking or thudding caused by a missing or deteriorated buffer.
• Protects Surrounding Components: Reduces unnecessary strain on suspension mounts and associated components.
• Supports Predictable Suspension Behaviour: Maintains the intended cushioning characteristics during heavy compression.
• Genuine Porsche Quality: Manufactured to the original specifications for the applicable rear suspension assembly.
• Correct Original Equipment Fitment: Designed to match the intended dimensions and installation requirements.
• Supports Long-Term Reliability: Helps prevent avoidable wear caused by excessive suspension impacts.
• Ideal During Shock Absorber Replacement: Provides an opportunity to renew ageing suspension protection components when the rear suspension is dismantled.
• Cost-Effective Preventative Maintenance: Replacing a relatively small protective component may help avoid damage to more expensive suspension parts.

Although the rear stop buffer is a relatively small component, it performs an important protective function within the suspension assembly.

A deteriorated or missing stop buffer can allow harsher suspension impacts, particularly when driving over uneven road surfaces or carrying heavier loads. Repeated excessive compression may place additional stress on the shock absorber and other suspension components.

Replacing the stop buffer with a Genuine Porsche part helps maintain the vehicle's original suspension performance and contributes to improved comfort, durability and long-term reliability.

Hose. 
The Genuine Porsche Air / Vacuum Hose (Part Number: 94411017802) is an original equipment engine intake system component designed for early Porsche 944 2.5L models equipped with factory air conditioning.

Fits:

• Porsche 944 2.5L 8V 1982-87

Diagram Ref No 29

This hose forms part of the engine's auxiliary air and vacuum system, working in conjunction with the electrically operated auxiliary air valve and associated intake components to maintain the intended air passages within the engine management system.

Manufactured to Porsche's original fitment specifications, the hose is designed to provide a secure, correctly routed connection between the relevant intake and auxiliary air components. Its moulded shape helps ensure correct positioning within the engine compartment while maintaining a properly sealed air passage.

The Porsche 944's 2.5L four-cylinder engine depends on correctly managed intake airflow to maintain stable idling, smooth engine operation and reliable performance. A damaged or leaking hose may allow unmetered air to enter the intake system, potentially affecting the air-fuel mixture and idle quality.

Over time, original rubber hoses can deteriorate as a result of engine heat, age, vibration and repeated thermal cycling. Rubber may become hard, brittle or cracked, particularly around connection points and hose bends.

A split or poorly sealed hose may cause an intake air leak, leading to rough idling, fluctuating engine speed or reduced drivability.

Replacing a deteriorated hose with a Genuine Porsche replacement helps restore the original intake system sealing arrangement, maintain correct auxiliary air operation and preserve the reliability of the engine's air management system.

Ideal for intake leak repairs, idle quality investigations, routine engine maintenance and classic Porsche restoration projects, this hose provides a factory-specified replacement for compatible early Porsche 944 models.

What This Product Does:
The Porsche 944 Air / Vacuum Hose is part of the engine's auxiliary air and intake system.

Its primary function is to provide a sealed air passage between the relevant intake components, supporting the operation of the electrically controlled auxiliary air valve.

The auxiliary air system helps manage additional airflow under certain operating conditions. The hose must remain correctly connected and airtight to ensure the system functions as intended.

If the hose becomes cracked, loose or disconnected, unwanted air may enter the intake system and interfere with the engine's normal fuel and air management.

Its main functions include:

• Providing an auxiliary air passage: Connects the relevant components within the engine's auxiliary air system.
• Maintaining intake system sealing: Helps prevent unwanted air from entering through damaged or poorly sealed connections.
• Supporting stable engine idling: Helps maintain the airflow conditions needed for consistent idle operation.
• Supporting auxiliary air valve operation: Provides the appropriate hose connection for the electrically controlled auxiliary air arrangement.

• Providing correct component routing: Uses the original hose shape to maintain the intended installation arrangement.
• Preserving factory functionality: Maintains the original Porsche intake system configuration.

Symptoms Of Wear Or Failure:
The original Porsche 944 air and vacuum hoses are exposed to engine heat, vibration, oil vapour and age-related deterioration.

On older vehicles, rubber components may lose flexibility, crack or become loose around their connections.

Common symptoms of a worn or damaged hose include:

• Rough engine idling: An intake air leak may disturb the air-fuel mixture, causing uneven engine operation.
• Fluctuating idle speed: The engine speed may rise and fall unexpectedly when the hose no longer seals correctly.
• High idle speed: Unmetered air entering the intake system may contribute to an abnormally high idle.
• Engine stalling: Severe air leaks may affect idle stability, particularly at low engine speeds.
• Hissing noises: A split or disconnected hose may produce an audible air leak around the intake system.
• Hard or brittle rubber: Ageing can cause the hose to lose flexibility and become more susceptible to cracking.
• Visible splits or cracks: Damage may appear around bends, hose ends or clamping areas.
• Loose hose connections: Deteriorated hose ends may no longer grip their fittings securely.
• Poor engine response: Intake air leaks may contribute to hesitation or inconsistent engine operation.
• Increased fuel consumption: Incorrect air-fuel management caused by significant air leaks may affect fuel efficiency.
• Cold-running irregularities: A fault in the auxiliary air circuit may contribute to unstable operation during warm-up.
• Damaged or collapsed hose sections: Physical deterioration may restrict the intended passage or prevent proper sealing.

Why Replacement Matters:
Replacing an ageing or damaged air hose is important for maintaining the integrity of the Porsche 944's intake system and supporting reliable engine performance.

Even small cracks or poorly sealed connections can allow unwanted air to enter the intake system, particularly when the engine is idling.

A damaged hose may also become increasingly brittle over time, making it more likely to split during engine servicing or normal operation.

Installing a Genuine Porsche replacement Air / Vacuum Hose helps to:

• Restore correct intake sealing: Replace damaged hose material and reduce unwanted air leakage.
• Improve idle stability: Help restore consistent engine idling where a leaking hose is contributing to irregular running.
• Maintain correct auxiliary air operation: Ensure the relevant air circuit is connected and sealed as intended.

Also described as a front stabiliser bar mounting bush or sway bar bearing, this component forms part of the mounting arrangement that holds the anti-roll bar in its correct position.

The anti-roll bar is an important element of the suspension system. It helps reduce excessive body roll during cornering by resisting differences in suspension movement between the left and right wheels.

For the anti-roll bar to work correctly, it must remain properly located within its mounting points while accommodating the controlled movement associated with suspension travel.

The Porsche bearing bracket 99134379207 provides this support, helping maintain the intended position of the front stabiliser bar and reducing unwanted movement within the mounting assembly.

On vehicles such as the Porsche 911 Carrera and mid-engined Boxster and Cayman, accurate suspension response is central to the driving experience.

Even relatively small suspension mounting components can influence the way loads are transmitted through the chassis.

Over time, anti-roll bar mounting bushes can deteriorate through repeated suspension movement, temperature changes, road contamination and general ageing.

Worn mounting material may develop cracks, compression or excessive clearance around the stabiliser bar.

When this happens, the anti-roll bar can move more than intended, potentially causing knocking, rattling or creaking noises from the front suspension.

Severe deterioration may also affect the consistency of the anti-roll bar's response during cornering.

Replacing a defective bearing bracket with Genuine Porsche part number 99134379207 helps restore the correct factory mounting arrangement, maintaining the original suspension characteristics.

What This Product Does

This cover belongs to the control-unit portion of the hydraulic anti-lock braking assembly. Its role is to cover that section in the arrangement identified by the relevant exploded diagram; it does not sense wheel speed, operate the pump or regulate hydraulic pressure.

Functions

• Provides the specified covering for the ABS/PSM control-unit section.
• Reinstates the cover position within the illustrated assembly.
• Allows renewal of a missing or damaged cover without identifying it as a complete control unit.

Technical Details

• Manufacturer: Porsche; part number: 99661803800.
• Diagram designation: cover control unit; also described as cover.
• Recorded quantity: 1 per illustrated assembly.
  
  

Symptoms of Fault

• Visible cracking, deformation or other damage to the cover.
• An uncovered control-unit section where the original component is missing.
• Poor seating or insecure retention when the cover is inspected.

Why Replacement Matters

Replacing a defective cover returns this part of the assembly to its specified layout. Inspect its seating and surrounding attachment points before fitting. Dashboard ABS/PSM alerts require separate fault investigation: a replacement cover is not a remedy for sensor, wiring, hydraulic or controller defects.

FAQs

Is the controller supplied with this cover?
No. The diagram treats 99661803800 as an individual cover, separate from the hydraulic assembly and its associated components.

Can this resolve an ABS warning?
The cover alone does not correct system faults. Diagnosis should assess stored faults, electrical supply, wiring, sensors and hydraulic operation as appropriate.

Vent Hose. 
The Genuine Porsche Vent Hose is a replacement cooling-system hose used within the coolant expansion-tank circuit of selected Porsche Cayenne 957 4.8-litre V8 models.

Fits:

• Porsche 957 Cayenne S / GTS 4.8L 2007-10
• Porsche 957 Cayenne Turbo / Turbo S 4.8L 2007-10  

Diagram Ref No 6

This hose connects into the engine cooling system and provides a controlled route between the coolant expansion tank and the engine cooling circuit. It helps manage coolant and displaced air as the cooling system heats, expands, cools and contracts.

Although commonly described as a vent hose, breather hose or coolant overflow hose, this component belongs to the engine cooling system. It is not a crankcase ventilation hose.

Correct venting is important because trapped air can interfere with coolant circulation and make the system difficult to bleed properly. The hose also needs to remain fully sealed so that coolant is retained and the pressurised cooling system can operate correctly.

Repeated exposure to hot coolant, cooling-system pressure and engine-bay temperatures can eventually cause the hose material to harden, split, swell or leak.

Replacing a deteriorated hose helps restore reliable coolant-system venting, correct expansion-tank operation and a sealed cooling circuit.

What This Product Does:
The vent hose forms part of the coolant expansion and deaeration circuit.

It is designed to:

• Connect the coolant expansion tank to the engine cooling circuit.
• Allow coolant and displaced air to move through the system.
• Help vent trapped air from the cooling circuit.
• Support correct cooling-system bleeding.
• Help maintain stable coolant pressure.
• Maintain a sealed coolant circuit.
• Support correct expansion-tank operation.
• Help prevent coolant loss.
• Replace a cracked, brittle or leaking original hose.
• Support stable engine operating temperature.

Symptoms Of Wear Or Failure:
Possible symptoms include:

• Visible coolant leakage.
• Dampness around the hose or its connections.
• Dried pink, white or coloured coolant residue.
• Sweet coolant smell from the engine compartment.
• Gradual coolant-level loss.
• Low coolant warning.
• Frequent need to top up coolant.
• Hose becoming hard or brittle.
• Surface cracks.
• Hose splitting.
• Swelling or bulging.
• Soft or spongy hose sections.
• Leakage around clamps.
• Difficulty bleeding the cooling system.
• Gurgling sounds within the coolant circuit.
• Fluctuating engine temperature.
• Steam from the engine compartment in severe cases.

Why Replacement Matters:
Replacing a worn or leaking vent hose helps restore:

• Correct cooling-system venting.
• Reliable expansion-tank operation.
• Stable coolant level.
• Correct coolant circulation.
• Cooling-system pressure.
• Reduced risk of airlocks.
• Reduced risk of coolant loss.
• Stable engine operating temperature.
• Long-term cooling-system reliability.
