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.

Radiator Intercooler.

Restore efficient charge-air cooling, correct boost-system operation and dependable turbocharged engine performance with these OE Match Radiator Intercoolers. Designed for compatible Porsche applications, these intercoolers form an important part of the engine's forced-induction and charge-air cooling system.

Fits:

• Porsche 971.1 Panamera 4 E-Hybrid V6 2.9L 4WD 2017-20
• Porsche 971.1 Panamera 4 E-Hybrid V6 2.9L 4WD Executive 2017-20
• Porsche 971.1 Panamera 4 E-Hybrid 2.9L Twin-Turbo V6 Sport Turismo 2017-20

Turbochargers compress the intake air before it enters the engine. Compression increases air pressure but also raises its temperature. The intercooler acts as a heat exchanger, removing excess heat from the compressed charge air before it reaches the engine.

Lowering charge-air temperature increases air density and helps the engine-management system maintain consistent performance, efficient combustion and controlled intake temperatures. This becomes particularly important during sustained acceleration, high engine loads and warm ambient conditions.

The intercooler also forms part of the pressurised intake circuit. Cracks, damaged connections, deteriorated seals or physical damage can allow boost pressure to escape, potentially resulting in reduced performance and underboost faults.

These OE Match Radiator Intercoolers provide high-quality replacements for damaged, leaking or inefficient original components.

What This Product Does:

• Cools compressed charge air from the turbocharging system.
• Reduces intake air temperature before the air reaches the engine.
• Helps increase the density of the boosted intake charge.
• Supports consistent turbocharged engine performance.
• Forms part of the pressurised charge-air circuit.
• Helps maintain the required boost pressure when properly sealed.
• Supports responsive acceleration and predictable power delivery.
• Helps maintain efficient combustion.
• Reduces thermal load within the intake system.
• Works with the turbocharger, charge-air pipework and engine intake.
• Helps maintain performance during sustained high-load operation.
• 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 or sluggish acceleration.
• Loss of turbocharger boost.
• Inconsistent power delivery.
• Check engine or engine-management warning light.
• Underboost-related diagnostic fault codes.
• Hissing or rushing-air noises during acceleration.
• Actual boost pressure failing to reach the requested value.
• Intermittent power loss under heavy load.
• Increased charge-air or intake temperatures.
• Engine entering a reduced-power or protective mode.
• Increased fuel consumption.
• Oil residue around intercooler joints or connections.
• Cracks in the intercooler or associated connections.
• Damaged or restricted cooling surfaces.
• Impact damage.
• Loose or leaking charge-air connections.
• Pressure loss detected during boost-system testing.  

Why Replacement Matters:

• An intercooler needs to perform two key functions effectively: remove heat from the compressed intake charge and maintain the integrity of the pressurised boost system.
• If an intercooler develops a leak, some of the compressed air supplied by the turbocharger can escape before reaching the engine. This may cause reduced boost pressure, poor acceleration and a noticeable loss of engine performance.
• The ECU may detect a difference between requested and actual boost pressure and record an underboost fault. Depending on the severity of the problem, the engine-management system may also limit performance to protect the engine and turbocharging system.
• Efficient heat transfer is equally important. If the intercooler becomes damaged, obstructed or internally compromised, charge-air temperatures can increase. Hotter intake air is less dense and can reduce the performance potential of the turbocharged engine.
• High intake temperatures may also cause the engine-management system to modify boost, ignition or other operating parameters to control thermal loads.
• Replacing a damaged or inefficient component with these OE Match Radiator Intercoolers helps restore charge-air cooling efficiency, boost-system integrity and consistent engine performance.
