Intercooler Sealing Ring, Upper Hose.
The OE Match Intercooler Sealing Ring, Upper Hose is a premium-quality replacement sealing component designed to provide an airtight connection between the upper intercooler hose and the intercooler assembly on compatible turbocharged Porsche models. Manufactured to OE specifications for fit, sealing performance and durability, this precision-moulded sealing ring prevents the loss of pressurised charge air, ensuring efficient turbocharger operation, optimum engine performance and consistent boost pressure.
  
Fits:

• Porsche 957 Cayenne 3.0L Diesel 2007-10
• Porsche 958 Cayenne V6 3.0L Diesel (245Hp) 2010-17  

Diagram Ref No 9

Manufactured from high-quality heat-, oil- and boost-resistant elastomer, the sealing ring is engineered to withstand elevated intake temperatures, turbocharger boost pressure, oil vapours and repeated thermal cycling without hardening, flattening or cracking. Precision-moulded to the original Porsche dimensions, it provides direct OE-style installation, making it ideal during intercooler servicing, boost pipe replacement or preventative maintenance.  

What This Product Does:

• Creates an airtight seal between the upper intercooler hose and intercooler.
• Prevents the loss of pressurised charge air.
• Maintains correct turbocharger boost pressure.
• Supports accurate engine air management.
• Helps optimise engine performance and fuel efficiency.
• Reduces the risk of boost leaks.
• Restores factory sealing performance.
• Forms an essential part of the turbocharger charge air system.

Symptoms Of Wear Or Failure:

• Loss of turbocharger boost pressure.
• Reduced engine performance.
• Delayed turbocharger response.
• Hissing noises under acceleration.
• Increased fuel consumption.
• Engine management warning light.
• Boost pressure or intake air leak fault codes.
• Oil residue around the upper intercooler hose connection.
• Hardened, flattened or cracked sealing ring.
• Difficulty maintaining consistent boost pressure.

Why Replacement Matters:

• The intercooler sealing ring is continually exposed to pressurised intake air, elevated temperatures, oil vapours and repeated thermal cycling. Over time, the sealing material naturally hardens, compresses or deteriorates, reducing its ability to maintain an effective airtight seal.
• A worn sealing ring can allow boost pressure to escape from the upper intercooler connection, reducing engine performance, throttle response and turbocharger efficiency. Continued operation with a boost leak may increase fuel consumption, trigger engine management fault codes and place unnecessary strain on the turbocharging system.
• Replacing the original component with the OE Match Intercooler Sealing Ring restores the integrity of the charge air system and ensures reliable boost pressure retention. Manufactured to OE standards using premium-quality sealing materials, it provides factory-style fitment, excellent durability and dependable long-term sealing performance, helping maintain the power, efficiency and reliability expected from your Porsche.

LIQUI MOLY Pro-Line Turbocharger Additive – 20g 

LIQUI MOLY Pro-Line Turbocharger Additive is a specialist lubricant designed to protect new turbochargers during installation and initial start-up.

Applied before the turbocharger oil supply line is connected, it helps prevent dry running and damage caused by insufficient lubrication during the initial running-in phase.

Vehicle Compatibility

• Porsche turbocharged petrol and diesel engines
• Other turbocharged vehicles

Suitable for all turbochargers and compatible with commercially available engine oils. Always follow the turbocharger manufacturer's installation instructions.

What Does It Do?

The additive provides initial lubrication to the turbocharger, protecting internal moving components before the engine oil supply is fully established.

Its emergency-running properties help reduce the risk of damage caused by temporary oil starvation during initial start-up.

Why Is It Important?

A newly installed turbocharger may not receive full engine oil pressure immediately after starting.

Without adequate initial lubrication, the turbocharger shaft and bearings can experience excessive friction and premature wear.

When Should It Be Used?

Use when installing a new or replacement turbocharger, before the engine is started.

It is particularly useful during turbocharger replacement, engine rebuilding and professional workshop repairs.

Checks & Application

Fill the turbocharger oil inlet passage completely with LIQUI MOLY Pro-Line Turbocharger Additive before connecting the oil supply line.

Ensure the turbocharger oil feed and return lines are clean and correctly installed. Follow the manufacturer's recommended priming and start-up procedures.

Key Features

• LIQUI MOLY Pro-Line professional workshop product
• Product reference 21651 20g plastic tube
• Protects against dry running during initial start-up
• Helps prevent damage from insufficient lubrication
• Excellent emergency-running properties
• Improves new turbocharger operational reliability
• Compatible with commercially available engine oils
• Suitable for all turbochargers

LIQUI MOLY Turbocharger Additives & Porsche Turbo Installation Products

Turbochargers operate at extremely high speeds and require a reliable oil supply to protect their internal bearings and rotating components.

LIQUI MOLY Pro-Line Turbocharger Additive provides additional protection during the critical initial start-up period following turbocharger installation.

Suitable for compatible Porsche turbocharged engines, it is a useful workshop product for turbocharger replacement and engine rebuilding.

The intercooler pipe O-ring sits between the mating surfaces of intercooler hoses, tubes, and connectors in the turbocharger charge air system. It prevents compressed air from leaking at these joints, ensuring that boost pressure flows efficiently from the turbocharger through the intercooler and into the engine. Maintaining a good seal here is essential for performance, responsiveness, and efficient engine operation under load.

Function
•  Seals intercooler hose connections: Prevents boost air leakage where pipes and connectors meet
•  Supports turbo efficiency: Helps maintain correct charge air pressure for optimal performance
•  Protects against pressure loss: Avoids reduced power and drivability issues from leaks
•  Durable elastomer: Designed to resist heat, pressure, and turbocharger system conditions

Intercooler pipe seals are small but critical to maintaining proper turbocharger performance. Over time, exposure to heat, pressure cycling, and engine bay contamination can cause original seals to:
•  Harden or become brittle
•  Distort or shrink
•  Leak compressed air at pipe joints
•  Reduce boost effectiveness

A leaking or degraded seal can result in loss of boost pressure, reduced engine power, slower acceleration, and poor throttle response. Replacing worn or damaged seals with quality OE Match units helps ensure a tight, leak-free joint and preserves the engineered performance of the turbocharger and intake system.

When to replace. Replace the intercooler pipe O-ring when:
•  You’re servicing intercooler hoses or charge air piping
•  You detect boost leaks (hissing during acceleration)
•  Engine performance feels reduced or inconsistent
•  Visual inspection shows the seal is brittle, cracked, or deformed
•  You’ve removed intercooler pipes and original seals were damaged
