## Overview

MANNOL 9201 Catalytic System Cleaner is a premium German-imported 500ml formula designed to remove carbon deposits and residues from valves, piston rings, catalytic converter cells, and oxygen sensors. By restoring optimal combustion and exhaust purification, it improves fuel efficiency, reduces emissions, and extends the lifespan of your catalytic converter and engine components. Ideal for professional-grade maintenance with an easy infusion method.

## Description

The Catalytic System Cleaner removes typical contamination and deposits in the combustion system: it cleans valves, piston rings, the exhaust system and the catalytic converter by eliminating carbon residues and scale, which ensures reliable operation and improved performance. It restores the optimal exhaust gases purification and decreases fuel consumption. All of this prolongs the service life of the catalytic converter and the combustion system. Connect the infusion device with the can. Insert the infusion needle into the engine rubber air intake vacuum tube and hang the can upside down to start the infusion. Let the engine run under stationary conditions at 1,500 rpm approximately for 30-45 minutes. Use this product outdoors. In case the exhaust manifold burns red due to high temperature of the catalytic converter, immediately stop the cleaning process.

## Features

- Cleans valves, piston rings, and catalytic converter cells, as well as the exhaust system, from carbon deposits, tar, and other residues;
- Removes carbon deposits from combustion chamber walls and piston ring grooves, preventing future buildup;
- Cleans oxygen sensor electrodes (lambda probe), improving sensor performance;

## Questions & Answers

**Q: How often should I use it on my car?**
A: It depends how old ur car or catalytic converter is.. i do it on every major maintenance..or 20000kms it keeps ur catalytic clean

**Q: How often should I use it on my car?**
A: Hi,
It depends on the condition of the car injectors and catalytic. In my opinion, I think every 20k KM if the injectors are much dirty and between 30-40k KM if you clean them on regular basis.
