Restore Lost Power and Performance to Your Diesel Engine
Is your diesel vehicle feeling sluggish? Suffering from rough idling, reduced acceleration, or increased fuel consumption? Over time, carbon deposits build up in the intake system, on intake valves, in the EGR valve, and around the turbocharger, robbing your engine of its efficiency and power.
The Liqui Moly Pro-Line Diesel Intake System Cleaner is a professional-grade, intensive cleaner designed to tackle these stubborn deposits head-on. This powerful formula effectively dissolves and removes harmful carbon buildup, restoring optimal airflow, combustion efficiency, and engine performance.
Key Features & Benefits:
-
✅ Removes Stubborn Carbon Deposits: Powerful formula effectively cleans and decarbonizes the entire intake tract, including hard-to-reach areas.
-
✅ Restores Engine Power & Throttle Response: By clearing blockages and deposits, it helps bring back lost horsepower and improves acceleration.
-
✅ Improves Fuel Economy: A cleaner intake system allows for more efficient combustion, which can lead to better fuel mileage.
-
✅ Cleans EGR Valves & Turbochargers: Specifically effective on components prone to heavy carbon fouling in modern diesel engines.
-
✅ Reduces Harmful Emissions: Helps lower smoke and particulate emissions by promoting more complete fuel combustion.
-
✅ Professional-Grade Strength: Part of the Liqui Moly “Pro-Line” series, indicating a high-performance product trusted by workshops.
How It Works:
This intensive cleaner is sprayed directly into the engine’s intake system (after the air mass meter) while the engine is running. The powerful solvents and active cleaning agents work to break down, dissolve, and flush away baked-on carbon deposits from the throttle valve, intake manifolds, intake valves, and the EGR system.
