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.
