Catalysts cleaner: Clean your converter thoroughly without disassembling. Stop the engine maintenance light from flashing and improve engine performance, making life easier. Energy saving & emission reduction: Reduce total hydrocarbon emissions by up to 50%, remove carbon deposits in catalytic converter, oxygen sensors, injectors and cylinder heads. Improve fuel efficiency, eliminate unpleasant odors and reduce fuel consumption. Protecting the motor: The cleaner contacts carbon deposits and impurities when flowing through the converter, effectively dissolving them. Active components chemically decompose these deposits, removing them from inner surfaces. Reduce fuel consumption & bad odour: Lower fuel consumption while eliminating long-term unpleasant smells. Proper fuel and exhaust make the engine run cleaner, quieter and better, reducing maintenance costs. Application: Safe for petrol, diesel, hybrid and fuel vehicles. No fuel change needed. Not suitable for two-stroke or oil/gas mixed engines. Notice: Actual color may vary slightly due to different light effects, as shown in the picture.
