Product Description

The Liqui Moly 20208 Pro-Line Diesel Intake System Cleaner is a premium-grade aerosol formula engineered to restore and maintain the intake manifold, throttle valve and EGR system components in diesel engines.

Ideal for service workshops or maintenance routines, this cleaner is designed for universal diesel fitment - whether for a passenger car, light commercial van or heavy-duty truck. The ready-to-use 400 ml aerosol makes it easy to apply without needing to dismantle large system components. Regular use supports fuel economy and engine durability.

When using this product, ensure the engine is at operating temperature, follow the manufacturer's service instructions, and observe all safety precautions for aerosol and solvent handling. This product is especially beneficial for diesel engines showing intake contamination symptoms such as rough idle, throttle lag, or increased emissions.
