## Effective Throttle, EGR and IAC Cleaning with Mannol 9873 Intake Valve Cleaner 400ml Mannol 9873 Intake Valve Cleaner 400ml is a highly effective tool for cleaning the intake system of gasoline engines, reaching even the intake valves and most inaccessible areas, without disassembly. A single application is often sufficient to restore the intake system to perfect condition. ### Problems with a dirty intake system? Over time, deposits accumulate on the IAC valve, affecting the flow of air and exhaust gases. This results in reduced power and acceleration, uneven idling, and increased fuel consumption. Symptoms of a clogged IAC valve include: * Difficulty starting the engine * Uneven idling (fluctuating RPM) * Slow RPM decrease after pressing the clutch pedal while driving * Black smoke from the exhaust pipe ### Advantages of Mannol 9873 Intake Valve Cleaner: * **Fast and effective cleaning:** Removes dirt, soot, carbon deposits, resinous and oil residues, even the most stubborn and old ones. * **Protection against corrosion and oxidation:** Protects the intake system components, preventing the formation of new deposits. * **Extends service life:** Ensures efficient operation and mobility of moving parts, resulting in a longer lifespan of the intake system and lower repair costs. * **Improves engine performance:** Facilitates cold starts, restores smooth idling, and reduces fuel consumption. * **Safe for catalytic converters, oxygen sensors, and turbochargers.** ### How to use: Shake the can well before use. Spray the product behind the air flow meter (avoid contact with the meter) for at least 30 seconds (depending on the level of contamination) with the engine running at idle (min. 2000 RPM). For persistent deposits on the throttle body, inside the intake manifold, or on the intake valves, repeat the cleaning procedure. After application, let the engine run for about 20 seconds at min. 2000 RPM to allow any residues in the intake system to burn off. **Caution:** Product contains acetone – aggressive to painted surfaces and plastics.
