Diagram Ref No 1

Located within the rear A/C refrigerant circuit, this pressure line carries pressurised refrigerant between components of the climate-control system. Correct refrigerant circulation is essential for the air-conditioning system to remove heat from the cabin and provide effective cooling.

As an original Porsche replacement component, the line is intended to restore the correct routing, sealing and pressure integrity of the factory air-conditioning system when the existing pipe has become corroded, damaged or has developed a refrigerant leak.

What This Product Does:
The air-conditioning system operates by continuously circulating refrigerant through a closed circuit containing the compressor, condenser, expansion components and evaporator.

This pressure line forms part of that sealed refrigerant circuit and transports refrigerant under pressure to the appropriate A/C components.

Its functions include:

• Carrying pressurised A/C refrigerant through the system
• Maintaining a sealed refrigerant circuit
• Supporting correct operation of the rear air-conditioning system
• Helping maintain the required refrigerant pressure
• Allowing efficient heat transfer and cabin cooling
• Maintaining the original factory refrigerant routing
• Providing a secure connection between A/C components

If the line cannot maintain a proper seal, refrigerant can escape and air-conditioning performance will progressively deteriorate.

Symptoms Of Wear Or Failure:
A/C refrigerant lines can deteriorate because of corrosion, vibration, road debris, repeated heat cycles or damage to connections and seals.

Common symptoms of a failing pressure line include:

• Air-conditioning no longer blowing cold air
• Reduced or inconsistent cooling performance
• Rear A/C noticeably warmer than expected
• Refrigerant level repeatedly becoming low
• A/C requiring frequent recharging
• Visible corrosion on the refrigerant pipe
• Cracks, dents or physical damage to the line
• Oily residue around the pipe or connection points
• Refrigerant dye visible around a leaking joint
• Hissing from the A/C system after shutdown
• Compressor cycling on and off more frequently than normal
• A/C system refusing to engage because refrigerant pressure is too low
• Loss of cooling shortly after the system has been recharged

An oily deposit is a common visual indication of leakage because small quantities of compressor oil circulate with the refrigerant and may escape with it.

Why Replacement Matters:

• The air-conditioning system must remain sealed to operate correctly. Even a small leak in a pressure line allows refrigerant to escape, gradually reducing the system's ability to cool the cabin.
• Operating the system with insufficient refrigerant can also reduce lubrication circulation through the compressor. If refrigerant loss is ignored for an extended period, this can contribute to more expensive A/C system problems.
• Replacing a leaking or corroded pressure line helps restore the sealed refrigerant circuit and enables the system to be correctly evacuated, leak-tested and recharged to the specified refrigerant quantity.
• Replacement is particularly important where corrosion has weakened the pipe, as a minor leak can eventually develop into a more substantial failure and lead to complete loss of air-conditioning performance.
• Because the A/C system contains refrigerant under pressure, servicing and recharging should be carried out using appropriate refrigerant recovery and charging equipment.

Water Pipe, Supply Tunnel. 

The Porsche Water Pipe, Supply Tunnel 98710665104 is a genuine Porsche replacement coolant supply pipe for selected 987 Boxster and Cayman models.
Fits:

• Porsche Boxster 987 2.7L 2005-08/08
• Porsche Boxster 987 MKII 2.9L 2009-12
• Porsche Cayman 2.7L 987C 2006-08
• Porsche Cayman 2.9L 987C MKII 2009-12  

Diagram Ref No 15

Running longitudinally through the vehicle's centre tunnel, this pipe forms part of the main liquid-cooling circuit connecting the rear-mounted engine with the front-mounted radiator system.

The Porsche 987 cooling system relies on long supply and return pipes to transport coolant between the engine and radiators. A secure, unrestricted supply pipe is therefore essential for maintaining coolant circulation, system pressure and stable engine temperature.

As a Genuine Porsche component, 98710665104 provides the factory-specified routing, dimensions and connection points for the applicable vehicle.
What This Product Does:
The centre-tunnel supply pipe carries coolant through the vehicle as part of the pressurised engine cooling system.

Its main functions include:

• Carrying coolant through the centre tunnel
• Connecting the rear engine cooling circuit with the front radiator circuit
• Maintaining continuous coolant circulation
• Helping maintain correct cooling-system pressure
• Supporting stable engine operating temperature
• Helping transfer heat away from the engine
• Maintaining the original Porsche coolant routing
• Providing a leak-free connection when correctly installed and sealed

The supply pipe works together with the corresponding return tunnel pipe to create the main coolant path between the engine and front radiators.
Symptoms Of Wear Or Failure:
Coolant pipes can deteriorate through age, corrosion, vibration, road contamination and repeated heat cycles.

Common symptoms include:

• Visible coolant leakage beneath the vehicle
• Coolant dripping from the centre tunnel area
• Pink, white or crusty coolant deposits
• Falling coolant level
• Frequent need to top up the expansion tank
• Low coolant warning
• Sweet coolant smell
• Corrosion or pitting on the pipe
• Damaged or distorted pipe sections
• Leakage around pipe connections or seals
• Cooling-system pressure loss
• Fluctuating engine temperature
• Higher-than-normal coolant temperature
• Steam or coolant vapour
• Engine overheating

Small leaks may only appear when the engine is fully warm and the cooling system has reached operating pressure.
Why Replacement Matters:
A leaking coolant supply pipe can reduce both coolant quantity and system pressure.

As coolant is lost, air may enter the system and circulation can become less effective.

Continued operation with a damaged pipe can contribute to:

• Loss of coolant
• Reduced cooling efficiency
• Cooling-system pressure loss
• Air pockets within the system
• Localised hot spots
• Engine overheating
• Reduced heater performance
• Coolant warning messages
• Roadside breakdown
• Serious engine damage if overheating becomes severe

Replacing a deteriorated tunnel pipe restores the integrity of the coolant circuit and helps maintain reliable temperature control.

Air Intake Resonator (Muffler). 

The Genuine Porsche Air Intake Resonator (Muffler) 99611022200 is an original equipment replacement component designed for the air intake system of early Porsche Boxster 986 models manufactured between 1997 and 1999.

Fits:

• Porsche Boxster 986 2.5L 1997-99

Diagram Ref No 9

Also referred to as an air intake muffler or intake noise damper, this component helps control the sound produced by air moving through the engine's intake system while maintaining the original Porsche intake arrangement.

The first-generation Porsche Boxster features a mid-mounted, naturally aspirated flat-six engine that relies on a carefully designed air intake system to supply filtered air to the engine.

During operation, the engine draws air through the intake housing and associated ducting towards the throttle body. The rapid opening and closing of the engine's intake valves, together with variations in airflow demand, create pressure fluctuations and sound waves within the intake system.

The air intake resonator is designed to influence these pressure fluctuations and help reduce certain frequencies of intake noise.

This allows Porsche to maintain a balance between the distinctive sound of its flat-six engine and the refinement expected during everyday driving.

Unlike an exhaust muffler, which reduces sound in the exhaust system, the intake resonator works on the engine's air intake side.

The original Porsche resonator forms part of the intake arrangement specified for early Boxster 986 vehicles.

Over time, ageing plastic components, repeated heat cycles, vibration or previous engine maintenance may cause the original resonator to crack, loosen or become damaged.

A damaged resonator can alter the normal intake sound and, if it creates an opening into the intake tract, may contribute to an unwanted air leak.

Loose or deteriorated mounting connections may also cause vibration or rattling during engine operation.

Replacing a damaged resonator with Genuine Porsche part number 99611022200 helps restore the original intake assembly, intended acoustic characteristics and secure component fitment.

This replacement is particularly suitable for Porsche owners carrying out engine intake maintenance, restoration or repairs to a cracked or missing original resonator.

Because this component is manufactured to the original Porsche specification, it is intended to retain the correct configuration of the early Boxster intake system.

What This Product Does:
The Porsche Air Intake Resonator is designed to help control intake sound and maintain the intended configuration of the engine's air induction system.

Its principal functions include:

• Reduces Intake Noise: Helps attenuate selected frequencies created by airflow and intake pressure fluctuations.
• Controls Intake Resonance: Influences acoustic pressure waves within the intake arrangement.
• Maintains Factory Intake Characteristics: Helps preserve the sound and refinement intended by Porsche.
• Supports Original Air Intake Configuration: Forms part of the specified early Boxster intake assembly.
• Helps Maintain Intake System Integrity: Provides the intended connection and enclosure when correctly installed.
• Reduces Unwanted Induction Sound: Helps prevent excessive intake roar caused by a damaged or missing resonator.
• Supports Secure Component Fitment: Replaces cracked or physically damaged intake parts.
• Maintains Original Porsche Specification: Allows the factory intake arrangement to be restored without an aftermarket conversion.

Symptoms Of Wear Or Failure:
Although the air intake resonator does not normally require replacement at fixed service intervals, its condition may deteriorate as the vehicle ages.

Common symptoms include:

• Visible cracks in the resonator body.
• Splits around connection points.
• Broken or damaged housing sections.
• Unusual intake noise.
• An air leak if the damage opens into the intake system.
• Louder induction noise.

Diagram Ref No 1

The pressure line carries hydraulic fluid under pressure through the power steering system, helping transfer hydraulic assistance to the steering rack when the steering wheel is turned.

Because the line operates under significant hydraulic pressure, secure fittings and leak-free pipework are essential. This genuine Porsche replacement is suitable for renewing an original pressure line that has become corroded, damaged, cracked or is leaking.
What This Product Does:
The hydraulic power steering system reduces the physical effort required to turn the front wheels.

The power steering pump circulates hydraulic fluid under pressure, while the pressure line carries this fluid towards the steering gear where hydraulic assistance is applied.

Its main functions include:

• Carrying pressurised power steering fluid
• Supplying hydraulic pressure to the steering system
• Supporting power-assisted steering operation
• Helping reduce steering effort
• Maintaining a sealed hydraulic circuit
• Supporting smooth and consistent steering response
• Maintaining the correct factory routing between steering components
• Preventing hydraulic fluid loss when correctly sealed

The pressure line itself does not generate hydraulic pressure; it safely transfers the pressure produced by the power steering pump.
Symptoms Of Wear Or Failure:
Power steering lines are exposed to hydraulic pressure, engine and road heat, vibration, moisture and ageing.

Common symptoms of a failing pressure line include:

• Visible power steering fluid leakage
• Wet or oily deposits around the line
• Leakage around unions or fittings
• Falling power steering fluid level
• Fluid stains beneath the vehicle
• Steering becoming heavier than normal
• Intermittent loss of steering assistance
• Whining or groaning from the power steering pump
• Noise when turning the steering wheel
• Foaming or aeration in the power steering fluid
• Cracked or deteriorated flexible hose sections
• Corrosion on metal pipe sections
• Damaged or distorted pipework
• Burning-fluid smell if leaked fluid reaches hot components

Heavy steering or pump noise can also be caused by a failing pump, steering rack or other hydraulic lines, so the complete system should be inspected before replacement.
Why Replacement Matters:
The power steering pressure line must contain hydraulic fluid at substantial operating pressure.

If the line develops a leak, the fluid level can gradually fall and hydraulic assistance may become weaker or inconsistent. A significant leak can eventually result in a noticeable increase in steering effort.

Continued operation with insufficient power steering fluid can also cause the pump to run without adequate lubrication and cooling, potentially resulting in expensive pump damage.

A deteriorated pressure line can also fail suddenly, causing rapid fluid loss.

Replacing a leaking or damaged pressure line helps restore:

• Correct hydraulic pressure
• Reliable power-assisted steering
• Consistent steering effort
• A sealed power steering circuit
• Correct fluid circulation
• Protection of the power steering pump and steering rack
• Factory-correct line routing and connections

Addressing a small leak early can therefore help prevent damage to more expensive steering components.

• Porsche 997 MKII Turbo 2010-13
• Porsche 997 MKII GT2 RS 2011-13  

Diagram Ref No 13

The hose connects into the pressurised engine cooling system and allows coolant to move correctly between the expansion reservoir and the associated cooling circuit.

Because the cooling system operates under pressure and experiences repeated heating and cooling cycles, maintaining this hose in good condition is essential for preventing coolant loss and maintaining stable engine temperatures.

As a Genuine Porsche component, 99710635000 provides the correct factory-style dimensions, routing and connection points for the intended application.

What This Product Does:
The coolant hose forms part of the expansion reservoir and cooling-system plumbing.

Its main functions include:

• Supporting correct filling and coolant movement
• Maintaining a sealed cooling system
• Helping maintain correct system pressure
• Allowing expansion and contraction of coolant as temperature changes
• Helping maintain the correct coolant level
• Supporting reliable engine temperature control
• Maintaining the original Porsche cooling-system routing

The hose works together with the coolant reservoir, bleed system, water pump, thermostat, radiators and remaining coolant pipework.

Symptoms Of Wear Or Failure:
Coolant hoses deteriorate gradually due to age, heat, pressure and repeated thermal cycling.

Common symptoms include:

• Visible coolant leakage
• Coolant staining around the hose
• Wetness around the expansion tank connection
• Pink, white or crusty dried coolant residue
• Falling coolant level
• Frequent need to top up coolant
• Low coolant warning
• Sweet coolant smell

• Hardened or brittle rubber
• Swollen or unusually soft sections
• Bulging when the system is pressurised
• Damaged hose ends
• Leakage around clamps
• Steam or coolant vapour after driving
• Fluctuating engine temperature
• Engine overheating in severe cases

Minor leaks may only become visible when the engine is fully warm and the cooling system has reached operating pressure.

Why Replacement Matters:
A leaking hose can gradually reduce the amount of coolant in the system.

If coolant loss continues, the system may no longer be able to control engine temperature effectively.

Continued operation with a damaged hose can result in:

• Coolant loss
• Loss of system pressure
• Air entering the cooling circuit
• Poor coolant circulation
• Localised hot spots
• Overheating
• Coolant warning messages
• Roadside breakdown
• Serious engine damage if overheating continues

Replacing a deteriorated hose helps restore a sealed cooling circuit and reliable coolant circulation.

Air Injection Pressure Line, Cyl. 1–3.

The Genuine Porsche Air Injection Pressure Line is a replacement component for the secondary air-injection system serving cylinders 1–3 on selected Porsche 911 (997) Turbo, GT2 and GT2 RS models.

Fits:

• Porsche 997 MK1 TURBO 2007-09
• Porsche 997 MK1 GT2 2007-09
• Porsche 997 MKII Turbo 2010-11
• Porsche 997 MKII GT2 RS 2011  

Diagram Ref No 13

The secondary air-injection system introduces fresh air into the exhaust system during specific operating conditions, particularly following a cold start. The additional oxygen helps promote oxidation of unburned exhaust gases and assists the catalytic converters in reaching effective operating temperature more quickly.

Because the system relies on controlled airflow, the pressure line must remain sealed, unrestricted and securely connected. Cracks, leaks, damaged connections or internal restriction can reduce secondary-air flow and may trigger emissions-related engine-management faults.

What This Product Does:
The air-injection pressure line transports air supplied by the secondary-air system towards the exhaust side of cylinders 1–3.

It is designed to:

• Carry secondary air to cylinders 1–3.
• Form part of the engine's emissions-control system.
• Help introduce additional oxygen into the exhaust stream during cold-start operation.
• Support faster catalytic converter light-off.
• Help reduce cold-start exhaust emissions.
• Maintain a sealed air path between secondary-air components.
• Support correct secondary-air system monitoring by the engine-management system.
• Replace a cracked, leaking, restricted or damaged original pressure line.
• Help restore correct secondary-air flow after an emissions-system fault.

Symptoms Of Wear Or Failure:
Possible symptoms include:

• Check Engine Light illuminating.
• Secondary-air injection fault codes.
• Insufficient secondary-air flow faults.
• Emissions-related diagnostic faults affecting the cylinder 1–3 bank.
• Hissing or blowing noise during cold-start secondary-air operation.
• Air escaping from a cracked line or damaged connection.
• Visible cracks or splits.
• Loose or damaged connections.
• Deteriorated sealing points.
• Secondary-air pump operating but expected airflow not reaching the engine.
• Increased cold-start exhaust emissions.
• Failed emissions or inspection testing where applicable.
• Repeated secondary-air system faults after other components have been checked.

Because the system operates primarily during specific cold-start conditions, a damaged pressure line may produce few noticeable drivability symptoms during normal warm-engine operation.

Why Replacement Matters:
The secondary-air system depends on a sealed route between the pump, control valves and exhaust injection points.

A leaking pressure line allows some of the supplied air to escape before reaching cylinders 1–3.

This can cause the engine-management system to detect insufficient secondary-air flow.

Replacing a faulty line helps restore:

• Correct secondary-air delivery.
• Proper system sealing.
• Reliable cold-start emissions control.
• Correct catalytic converter warm-up strategy.
• Reduced likelihood of secondary-air diagnostic faults.
• Proper operation of the cylinder 1–3 air-injection circuit.
