This component forms part of the engine's charge-air cooler and pressure-pipe assembly, which manages the compressed intake air supplied by the turbocharging system.

The Porsche Macan 3.0L and 3.6L turbocharged engines use charge-air coolers, connecting pipes, flexible hoses and associated components to deliver compressed air to the engine.

Maintaining secure connections throughout this system is important for consistent engine operation, accurate pressure management and reliable turbocharger performance.

Porsche part number 95B145979A is identified as a pressure hose within the charge-air cooler assembly.

It is a smaller hose within this system and should not be confused with the larger charge-air delivery hoses connecting the turbochargers, intercoolers and main intake pipework.

The hose provides the specified connection within the charge-air system, helping maintain the intended pressure or vacuum circuit associated with the assembly.

Manufactured to Porsche's original equipment specifications, this Genuine Porsche replacement is intended to provide the correct fit and connection arrangement for compatible vehicles.

During normal operation, the hose is exposed to engine compartment temperatures, vibration, changes in pressure and environmental contamination.

Over time, flexible hoses can deteriorate because of heat, ageing, mechanical stress or contact with surrounding components.

The material may become brittle, cracked, hardened or damaged around the connection points.

A damaged or disconnected pressure hose can compromise the integrity of its circuit and may contribute to incorrect pressure behaviour or engine performance problems.

Replacing a deteriorated hose with the correct Genuine Porsche component helps restore the original connection, maintain the intended system arrangement and support dependable engine operation.

Ideal for Porsche Macan engine servicing, charge-air system repairs, turbocharger-related diagnostics and routine hose replacement, this Genuine Porsche Charge-Air Pressure Hose provides a factory-specified replacement for the appropriate V6 applications.

What This Product Does:
The charge-air pressure hose provides a connection within the engine's charge-air cooler and pressure-pipe assembly.

Turbocharged engines compress incoming air before it enters the engine. This process increases air temperature, so the air is passed through charge-air cooling components before being delivered to the intake system.

The complete arrangement relies on secure hoses, seals, clamps and pipe connections.

Part number 95B145979A forms part of this assembly and helps maintain the integrity of its designated pressure-related connection.

Its main functions include:

• Maintaining the specified hose connection: Links the corresponding components within the charge-air assembly.
• Supporting pressure-system integrity: Helps prevent unwanted leakage from the connected circuit.
• Maintaining correct hose routing: Follows Porsche's original connection arrangement.
• Accommodating engine vibration: Provides flexibility between the associated components.
• Supporting reliable turbocharged engine operation: Helps maintain the intended condition of the charge-air system.
• Reducing unwanted air leakage: Provides a serviceable connection when correctly installed.
• Maintaining original component fitment: Matches the designated Porsche installation.
• Supporting accurate system operation: Helps prevent faults arising from a damaged or disconnected hose.
• Allowing targeted maintenance: Enables replacement of a defective hose without unnecessarily replacing the entire charge-air assembly.
• Preserving factory construction: Maintains the original Porsche hose configuration.

Symptoms Of Wear Or Failure:
A pressure hose within the turbocharged intake system may deteriorate because of heat, vibration, contamination or damage during previous repairs.

Common signs of wear or failure include:

• Visible cracks: Ageing or excessive heat may cause surface cracking.
• Hardened hose material: Deterioration may reduce flexibility.
• Split hose ends: Cracks can develop where the hose connects to a fitting.
• Loose hose connections: A damaged clamp or hose end may allow movement.
• Disconnected hose: The hose may become detached from its original connection.
• Visible abrasion: Contact with surrounding components may wear through the hose surface.
• Flattened or kinked hose: Incorrect routing may restrict the intended passage.
• Softened or swollen material: Exposure to incompatible fluids or contaminants may damage the hose.
• Damaged retaining clamp: A corroded or incorrectly fitted clamp may prevent secure attachment.
• Air leakage from the connected circuit: A split or insecure hose may compromise pressure or vacuum integrity.
• Engine warning light: A significant fault affecting pressure control or monitoring may trigger a diagnostic warning.
• Reduced engine response: Certain charge-air system leaks can affect turbocharged engine performance.
• Inconsistent acceleration: Pressure-system faults may contribute to irregular engine response.
• Unusual air leakage noises: A defective connection may produce audible leakage under relevant operating conditions.
• Repeated pressure-related diagnostic faults: Fault codes may indicate the need to inspect the associated hoses and connections.

Why Replacement Matters:
Replacing a damaged charge-air pressure hose helps maintain the integrity of the engine's original pressure-related connections.

Even a relatively small hose can be important to the correct operation of its associated system.

A cracked, loose or disconnected hose may allow unwanted leakage, interfere with pressure behaviour or prevent the connected components from functioning as intended.

Continued use of a damaged hose can make fault diagnosis more difficult and may contribute to further deterioration.

Installing a Genuine Porsche replacement Charge-Air Pressure Hose helps to:

• Restore the original connection: Replace a defective hose with the specified component.
• Reduce unwanted air leakage: Address leaks caused by cracks or damaged hose ends.
• Maintain pressure-system integrity: Preserve the intended operating condition of the connected circuit.
• Support reliable engine performance: Help ensure the charge-air system operates correctly.
• Replace heat-damaged material: Renew hoses affected by prolonged engine compartment temperatures.
• Restore secure attachment: Replace a hose that no longer remains firmly connected.
• Prevent further deterioration: Address cracks and abrasion before the hose fails completely.
• Support accurate engine diagnostics: Eliminate a confirmed defective connection as a possible fault source.
• Maintain correct routing: Preserve Porsche's intended hose position and configuration.
• Support turbocharger system maintenance: Restore the associated charge-air assembly.
• Maintain original equipment fitment: Use the correct Porsche component.
• Avoid unsuitable universal hose substitutions: Preserve the intended dimensions and connection characteristics.
• Support long-term engine reliability: Maintain a sound hose connection within the engine system.

Replacement is recommended when the hose is cracked, split, hardened, swollen, abraded, kinked or unable to remain securely attached.

Where the mating connections or retaining clamps are damaged, these components should also be inspected and renewed as necessary.
