Kalimex JLM Petrol Catalytic Converter Cleaner (J03150)

JLM Petrol Catalytic Converter Cleaner is a specially developed, unique combination of additives that rapidly ensures the correct function of the catalytic converter, reduces fuel consumption and remedies power loss due to contamination. This makes JLM Petrol Catalytic Converter Cleaner the ideal product for the professional car mechanic to use before an emissions test (e.g. before the MOT test).

JLM Petrol Catalytic Converter Cleaner cleans the entire fuel system and prevents fouling of the catalytic converter. In contrast to most other products, JLM Petrol Catalytic Converter Cleaner also contains a ‘combustion improver’ which brings about an immediate improvement in the engine combustion (even before the cleaner has actually cleaned the entire fuel system) and this is immediately reflected in lower emissions. This means that the car will pass the emissions test in the MOT test more easily, so the customer is back on the road sooner. 

JLM Petrol Catalytic Converter Cleaner is a highly concentrated cleaner that remedies and minimizes carbon deposits and contamination in cars fitted with a catalytic converter. Cleaning the fuel system, valves, pistons and injectors makes combustion more efficient, which in turn leads to lower emissions and prevents contamination of the catalytic converter.
