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.

Manufactured from high-quality automotive-grade composite materials with a durable diaphragm or piston assembly (application dependent), precision-engineered internal components and high-temperature-resistant seals, the shut-off valve is designed to withstand high boost pressures, engine bay temperatures, vibration and continual operating cycles. Designed as a direct replacement for the original component, it integrates seamlessly with the turbocharger, intake system and engine management system, delivering factory-correct performance and dependable operation.  

What This Product Does:
  • Releases excess boost pressure when the throttle closes.
  • Prevents compressor surge within the turbocharger.
  • Protects the turbocharger from unnecessary stress.
  • Improves throttle response during gear changes.
  • Maintains smooth turbocharger operation.
  • Supports efficient engine performance and drivability.
  • Restores factory boost pressure control.
  • Forms an essential part of the turbocharging and intake system.

Symptoms Of Wear Or Failure:
  • Loss of turbo boost pressure.
  • Reduced engine performance.
  • Sluggish acceleration.
  • Fluttering or chattering noises from the turbocharger during throttle lift-off.
  • Hissing noises caused by boost leaks.
  • Illuminated engine management or check engine warning light.
  • Engine management fault codes relating to boost pressure.
  • Poor throttle response.
  • Increased fuel consumption.
  • Inconsistent turbocharger performance.

Why Replacement Matters:
  • The turbocharger shut-off valve operates every time the throttle is released while the turbocharger is producing boost pressure. It is continually exposed to high boost pressures, rapid pressure fluctuations, elevated temperatures and constant engine vibration. Over time, the internal diaphragm, piston, spring or seals can wear, crack or lose their ability to seal correctly.
  • A faulty shut-off valve can cause boost leaks, compressor surge and inconsistent turbocharger performance, resulting in reduced engine power, slower throttle response and increased stress on the turbocharger. Continued operation with a defective valve may accelerate wear of the turbocharger and reduce overall engine efficiency.
  • Replacing a worn or faulty valve with a Genuine Porsche component restores precise boost pressure regulation and protects the turbocharging system from unnecessary wear. Manufactured to Porsche's exact engineering standards, the Genuine Porsche Turbocharger Shut-Off Valve provides factory-correct fitment, exceptional durability and long-lasting reliability, ensuring the performance, efficiency and driving experience expected from your Porsche.

About Turbo Chargers / Intercoolers & Parts

Turbochargers, Intercoolers & Parts – Precision-Engineered Performance for Porsche Engines

A turbocharger increases your Porsche’s power and efficiency by forcing more air into the engine’s combustion chamber, while the intercooler cools that compressed air to improve performance and reliability. Together, these components deliver the exhilarating acceleration and responsiveness that define Porsche engineering.

At Design911, we offer a comprehensive selection of turbochargers, intercoolers, and related components for Porsche models old and new. Manufactured using high-grade materials and advanced balancing technology, our range ensures consistent boost pressure, superior cooling efficiency, and long-term durability under extreme conditions.

Whether you’re restoring a classic 911 Turbo, upgrading a Cayman for track use, or replacing worn components on a modern model, our high-quality turbo and intercooler parts guarantee unmatched performance and reliability.

What Do Turbochargers & Intercoolers Do?

Turbochargers and intercoolers work together to enhance engine power, efficiency, and response.

Core Functions:

  • Turbocharger: Compresses intake air to increase the engine’s air/fuel ratio, producing greater power.
  • Intercooler: Reduces the temperature of compressed air before it enters the engine, improving combustion and preventing knock.
  • Associated Parts: Turbo hoses, valves, clamps, and cooling lines maintain consistent boost pressure and reliable airflow.

Together, these systems optimise power delivery, throttle response, and engine longevity — key to achieving Porsche’s hallmark driving experience.

Why Do Turbochargers & Intercoolers Fail?

Turbo and intercooler systems operate under extreme temperatures and pressure. Over time, wear and heat cycling can cause performance degradation or failure.

Common Causes of Failure Include:

  • Oil contamination or starvation damaging the turbo bearings.
  • Boost leaks from worn seals, cracked hoses, or gaskets.
  • Intercooler clogging due to debris or oil residue.
  • Excessive exhaust temperatures leading to turbine damage.
  • Corrosion or heat fatigue from prolonged high-speed driving.

Symptoms of failure include whining noises, loss of power, blue or black exhaust smoke, poor boost response, or oil leaks around the turbo system. Addressing these early can prevent costly repairs and maintain performance.

Why Replace Components?

Replacing a worn turbocharger or intercooler with a precision-engineered, high-performance alternative restores full boost pressure, temperature control, and efficiency — ensuring your Porsche performs as intended.

Key Benefits:

  • Restores boost pressure and throttle response.
  • Improves air cooling and power delivery.
  • Prevents oil and boost leaks.
  • Constructed from lightweight, heat-resistant materials.
  • Direct-fit compatibility for Porsche 911, Cayman, Boxster, Macan, Panamera and more.
  • Ideal for performance upgrades, maintenance, or rebuilds.

High-quality turbo and intercooler components are essential for reliable, sustained performance in both road and track environments.

Highlights:

  • Turbochargers, intercoolers & related parts for Porsche models.
  • Precision-engineered to enhance airflow, boost, and cooling.
  • Heat-resistant construction ensures durability and performance.
  • Perfect for maintenance, upgrades, or complete rebuilds.
  • Supports Porsche 911, Cayman, Boxster, Panamera and more.
  • Optimised for performance and reliability under extreme load.
