Diagram Ref No 1

The intercooler is a key component in a turbocharged engine's induction system. As the turbocharger compresses intake air, the temperature of that air rises. The intercooler acts as a heat exchanger, removing excess heat from the compressed air before it reaches the engine.

Cooling the charge air increases its density and helps the engine receive the intended mass of air under boost. This supports consistent performance, efficient combustion and controlled intake temperatures, particularly during acceleration and sustained high-load operation.

The intercooler also forms part of the pressurised boost circuit and therefore needs to remain properly sealed. Cracks, damaged end sections, leaking connections or impact damage can allow compressed air to escape, resulting in reduced boost pressure and performance.

This OE Match Left Radiator Intercooler provides a high-quality replacement for a damaged, leaking or inefficient original component.

What This Product Does:

• Is specified for the LEFT-side application.
• Cools compressed air produced by the turbocharging system.
• Reduces charge-air temperature before air enters the engine.
• Helps increase the density of the boosted intake charge.
• Forms part of the pressurised charge-air circuit.
• Helps maintain correct boost pressure when properly sealed.
• Supports consistent turbocharged engine performance.
• Helps maintain responsive acceleration.
• Supports efficient combustion.
• Helps control intake temperatures under load.
• Works with the turbocharger, charge pipes and intake system.
• Helps maintain predictable engine performance during demanding driving.
• Replaces a leaking, damaged or inefficient intercooler.
• Provides an OE Match alternative for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Reduced engine power. Poor acceleration.
• Loss of turbocharger boost.
• Sluggish throttle response.
• Check engine or engine-management warning light.
• Underboost-related diagnostic fault codes.
• Hissing or rushing-air noises under acceleration.
• Boost pressure failing to reach the requested level.
• Intermittent power loss under load.
• Increased intake air temperatures.
• Engine entering reduced-power or protective mode.
• Increased fuel consumption.
• Oil residue around an intercooler leak or connection.
• Cracks in the intercooler core or end sections.
• Bent or heavily damaged cooling fins.
• Impact damage from road debris.
• Leaking intercooler connections.
• Damaged inlet or outlet connections.
• Pressure loss found during charge-air system testing.  

Why Replacement Matters:

• A properly functioning intercooler has two essential jobs: removing heat from the compressed intake air and maintaining a sealed boost circuit.
• If the intercooler develops a crack or leak, compressed air can escape before reaching the engine. This reduces the amount of boost available and may cause poor acceleration, reduced power and underboost diagnostic faults.
• The engine-management system continually compares requested and measured operating conditions. A significant boost leak can cause the ECU to detect that actual pressure is below the expected value and, depending on the severity of the fault, activate a reduced-power strategy.
• Cooling efficiency is equally important. If the intercooler core becomes damaged, heavily obstructed or otherwise inefficient, intake air temperatures can increase. Hotter air is less dense, which can reduce performance and cause the engine-management system to adjust operation when thermal limits are approached.
• A substantial boost leak may also cause the turbocharging system to work harder in an attempt to reach the requested pressure, depending on the engine's control strategy.
• Replacing a defective component with this OE Match Left Radiator Intercooler helps restore charge-air cooling, boost-system integrity and consistent turbocharged engine performance.

Radiator Intercooler.

Maintain efficient charge-air cooling and dependable turbocharged engine performance with this Porsche Radiator Intercooler, part numbers 95514580301 and 95511080402. Designed for compatible Porsche applications, the intercooler is a key part of the turbocharging and intake system, reducing the temperature of compressed intake air before it enters the engine.

Fits:

Diagram Ref No 1 And 2

Turbochargers compress the intake air to increase the amount of oxygen available for combustion. However, compressing air also increases its temperature. Hotter air is less dense and can increase thermal stress, so the intercooler acts as a heat exchanger to remove excess heat from the boosted intake charge.

By cooling the compressed air, the intercooler helps provide a denser intake charge, supporting consistent engine performance, efficient combustion and controlled intake temperatures.

Intercoolers operate under pressure and are continually exposed to heat cycles, vibration and road conditions. Over time, the core, end tanks, seals or connections can deteriorate or become damaged. A leaking intercooler can allow boost pressure to escape, potentially causing reduced power, poor acceleration and engine-management faults.

Replacing a damaged or leaking unit with the correct Porsche Radiator Intercooler 95514580301 / 95511080402 helps restore charge-air cooling efficiency and a properly sealed boost system.

What This Product Does:

• Cools compressed air produced by the turbocharging system.
• Reduces intake air temperature before air enters the engine.
• Helps increase the density of the boosted intake charge.
• Supports consistent turbocharged engine performance.
• Helps maintain efficient combustion.
• Supports predictable power delivery under load.
• Forms part of the pressurised charge-air system.
• Helps maintain correct boost pressure when properly sealed.
• Reduces thermal load within the intake system.
• Works with the turbocharger, boost pipework and intake system.
• Helps the engine-management system achieve expected performance.
• Replaces a leaking, damaged or inefficient intercooler.  

Symptoms Of Wear Or Failure:

• Reduced engine power.
• Poor acceleration.
• Loss of turbocharger boost.
• Sluggish throttle response.
• Engine-management or check engine warning light.
• Underboost-related diagnostic fault codes.
• Hissing or rushing-air noises during acceleration.
• Boost pressure that does not reach the expected level.
• Intermittent loss of performance under load.
• Increased intake air temperatures.
• Engine entering a reduced-power or protective mode.
• Increased fuel consumption.
• Oil residue around intercooler joints or damaged areas.
• Cracks in the intercooler core or end sections.
• Bent or heavily damaged cooling fins.
• Impact or road debris damage.
• Leaking intercooler connections.
• Pressure loss detected during charge-air system testing.  

Why Replacement Matters:

• The intercooler must perform two important functions: cool the compressed intake charge and maintain a sealed path for boost pressure.
• If the intercooler develops a crack or leak, compressed air can escape before reaching the engine. The turbocharger may still be producing boost, but part of that pressure is lost through the damaged intercooler.
• This can result in reduced engine performance, slower acceleration and underboost fault codes. The engine-management system may also limit power if measured boost pressure differs significantly from the requested value.
• Cooling efficiency is equally important. A damaged, contaminated or heavily obstructed intercooler may be less effective at removing heat from the intake charge. Higher intake temperatures reduce air density and can cause the engine-management system to modify operation to protect the engine under demanding conditions.
• Continuing to operate with a substantial boost leak can also make the turbocharging system work harder to achieve requested pressure, depending on the engine and control strategy.
• Replacing a defective intercooler with the correct Porsche Radiator Intercooler 95514580301 / 95511080402 helps restore charge-air system integrity, effective intake cooling and consistent turbocharged engine performance.
