Just connect it to the air intake, let the engine idle, and the cleaner does the work. - Helps Clear That Check Engine Light: A clogged or inefficient catalytic converter is one of the most common reasons for a check engine light. This catalyst cleaner restores converter efficiency by removing the buildup that triggers fault codes, potentially saving you from an expensive replacement. - Brings Back Lost Engine Power: Carbon deposits in the exhaust system create resistance that robs your engine of power. This exhaust system cleaner reduces that hydrodynamic resistance, helping restore the original power output your engine was designed to deliver. - Also Cleans the Fuel System and Injectors: Beyond the catalytic converter, this cleaner also works on the fuel supply system and fuel injection devices. It removes typical contaminants from fuel injectors without disassembly — one product that cleans from the intake all the way through the exhaust. - Works on All Gasoline Engines: Suitable for all gasoline engines, both naturally aspirated and turbocharged. This engine carbon cleaner helps reduce fuel consumption and exhaust emissions by optimizing the combustion process and eliminating contamination throughout the fuel and exhaust systems. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0744LYJ84 | | Best Sellers Rank | #523,656 in Automotive ( See Top 100 in Automotive ) #279 in Fuel Additives #1,098 in Cleaners | | Brand | MANNOL | | Customer Reviews | 4.0 4.0 out of 5 stars (127) | | Date First Available | June 1, 2023 | | Is Discontinued By Manufacturer | No | | Item Weight | 1.1 pounds | | Item model number | 9201 | | Manufacturer | SCT Lubricants | | Manufacturer Part Number | 9201 | | Model | 9201 Catalytic System Cleaner | | Product Dimensions | 4.33 x 2.36 x 7.48 inches | ## Images ![MANNOL Catalytic Converter Cleaner, MN9201, Professional Catalytic System Cleaner for All Gasoline Engines, Cleans Valves, Piston Rings, Exhaust System, and Fuel Injectors Without Disassembly - Image 1](https://m.media-amazon.com/images/I/71t-aj5z8OL.jpg) ![MANNOL Catalytic Converter Cleaner, MN9201, Professional Catalytic System Cleaner for All Gasoline Engines, Cleans Valves, Piston Rings, Exhaust System, and Fuel Injectors Without Disassembly - Image 2](https://m.media-amazon.com/images/I/81T00MYht8L.jpg) ![MANNOL Catalytic Converter Cleaner, MN9201, Professional Catalytic System Cleaner for All Gasoline Engines, Cleans Valves, Piston Rings, Exhaust System, and Fuel Injectors Without Disassembly - Image 3](https://m.media-amazon.com/images/I/91GDBKrHGjL.jpg) ![MANNOL Catalytic Converter Cleaner, MN9201, Professional Catalytic System Cleaner for All Gasoline Engines, Cleans Valves, Piston Rings, Exhaust System, and Fuel Injectors Without Disassembly - Image 4](https://m.media-amazon.com/images/I/812zmZhkUDL.jpg) ![MANNOL Catalytic Converter Cleaner, MN9201, Professional Catalytic System Cleaner for All Gasoline Engines, Cleans Valves, Piston Rings, Exhaust System, and Fuel Injectors Without Disassembly - Image 5](https://m.media-amazon.com/images/I/91LoFaDBEaL.jpg) ## Frequently Bought Together - MANNOL 9201 CATALYTIC SYSTEM CLEANER - Professional O.E.M.
