What the Product Does

• Provides a secure, leak-free seal between intercooler pipes and housings.
  
• Maintains consistent turbo boost pressure by preventing leaks.
  
• Helps the intercooler system deliver cool, dense air to the engine for improved combustion.
  
• Reduces the risk of contaminants entering the intake system.

Common Symptoms of Seal Failure

When the intercooler pipe seal ring begins to wear or fail, you may notice:

• Loss of power or poor acceleration due to boost leaks.
  
• Hissing or whistling noises under acceleration.
  
• Check Engine Light with fault codes relating to boost pressure.
  
• Reduced fuel efficiency from improper air-fuel mixture.
  
• Excessive smoke from the exhaust caused by incorrect combustion.
  
• Oil residue or wetness around the intercooler pipes.

Reasons for Failure

These seals operate under constant pressure, temperature extremes, and exposure to oil mist.
Common causes of failure include:

• Age-related hardening of the rubber material.
  
• Heat cycles and pressure fluctuations causing cracks or deformation.
  
• Oil contamination breaking down sealing properties.
  
• Wear and tear from frequent pipe removal and refitting during servicing.
  
• Improper installation or misalignment of the pipe.

Why Replacement is Important
A failing intercooler seal ring can lead to significant performance and reliability issues.
Replacing it ensures:

• Restored engine power by eliminating boost leaks.
  
• Improved fuel economy and combustion efficiency.
  
• Protection of the turbocharger and engine from excess strain caused by leaks.
• Prevention of further costly damage to hoses, pipes, or intake components.
  
• Long-term reliability of your vehicle’s turbocharging system.
