Catalytic-System Cleaner is a 300 ml intake-applied cleaner for gasoline engines with catalytic converters. It is designed to clean intake valves and combustion chambers, improve fuel combustion, protect the catalytic converter from soot blockage and help prevent fuel-system corrosion. This is not a pour-in fuel-tank additive: LIQUI MOLY specifies controlled atomization through its Pump-Spray Bottle into the intake immediately behind the air-flow sensor while the engine runs at moderate speed. Correct dosing and access location are essential.
