Catalyst cleaner: clean your converter thoroughly with the catalyst cleaner without disassembling it. Stop the dreaded engine maintenance light flashing on your display and achieve better engine performance. Makes life easier. Protect the motor: the cleaner comes into contact with the carbon deposits and impurities when flowing through the converter and dissolves them effectively. The active components chemically decompose these deposits so they can be removed and dissolved from the inner surfaces of the converter. Reduce fuel consumption and bad odour: while reducing fuel consumption, the unpleasant smell that accumulates in your car over time is also eliminated. The right fuel and the right exhaust fumes ensure that the engine runs cleaner, quieter and better, which also reduces maintenance costs. Area of application: catalyst cleaner. Safe for petrol, diesel, hybrid and flex fuel vehicles, without fuel change, not for 2-stroke or oil/gas mixed engines.
