## Overview

MANNOL 9201 Catalytic System Cleaner is a professional-grade additive designed to remove carbon deposits and scale from combustion components including valves, piston rings, exhaust, and catalytic converters. By restoring optimal exhaust purification and reducing fuel consumption, it enhances engine performance and extends catalytic converter life. Applied via direct infusion into the engine air intake, it’s a must-have for maintaining efficient, clean-running vehicles.

## 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.

Review: Waste of money - I’ve followed carefully the instructions but unfortunately the product had no effect and didn’t clean anything inside the cylinder (check by endoscope after cleaning)
Review: I was unaware this had to be injected into the intake system
