Charge air cooler / intercooler - sits between the turbocharger compressor outlets and the intake manifold to cool boosted air before it enters the engine.

Diagram ref no 1
An intercooler is a key component in a turbocharged engine’s induction system, used to remove heat from compressed intake air before it enters the engine. Cooler, denser air supports better combustion efficiency, higher power output, and reduced likelihood of detonation - all of which help maximize performance and reliability.
The intercooler cools the pressurised air coming from the turbocharger(s) before it enters the engine intake. As air is compressed by the turbocharger, its temperature rises; the intercooler dissipates this heat so the engine receives cooler, denser charge air, which enhances:
• Power and torque output
• Combustion efficiency
• Fuel economy
• Engine durability
Without an effective charge air cooler, hot intake air can reduce performance and increase the risk of engine knock or thermal stress under load.
Function:
• Heat exchange between compressed intake air and ambient air to reduce intake charge temperature.
• Supports consistent power delivery under repeated boost cycles.
• Helps protect internal engine components from high thermal loads.
Turbocharged engines depend on efficient intercooling to keep intake temperatures under control. Over time, original intercoolers can become:
• Clogged with oil or debris
• Corroded or damaged by road debris
• Less effective at heat dissipation
When an intercooler’s performance degrades, you can experience:
• Reduced power and throttle response
• Increased intake air temperatures
• Higher risk of engine knock
• Reduced fuel efficiency
Replacing a worn or leaking intercooler restores proper cooling capacity, helps maintain turbo performance and boost consistency, and supports long-term engine health.
Replace the charge air cooler if you notice:
• Reduced engine performance or throttle response
• Heat-soak symptoms under repeated boost cycles
• Oil or residue inside the intercooler
• Visible physical damage or corrosion
• During a turbo system overhaul or maintenance involving charge piping
