First, create access to the intake system, as close as possible to the engine and downstream of the air flow meter and start the engine to start cleaning.

If the engine cannot maintain the speed with the intake pipe removed or cannot be started, disconnect the plug from the air flow meter with the ignition switched off. In this case, the fault code must be deleted from the ECU after cleaning using a suitable diagnostic device and the air flow meter must be taught in again if necessary.

Then, spray this product into the intake system with the spray hose in short intervals of 2 – 3 seconds while maintaining minimum 2,000 RPM. Move the probe back and forth in the process to clean the entire intake tract.

If a speed increase of more than 1,000 revolutions occurs during application, stop the spraying process immediately.

After use, allow the engine to run for about 20 seconds at min. 2,000 revolutions in order to burn any residues remaining in the intake system.

In the case of stubborn deposits on the EGR valve, in the intake manifold or on the intake valves, we recommend to repeat the cleaning process with a second can of this product.

No. This product cleans the stubborn dirt on the intake system area by dissolving the dirt, then removed from the engine through the exhaust during combustion. The content also evaporates without leaving any residues on the intake area.

This product may attack certain plastic or rubber parts sensitive to solvents. Please make sure not to spray this product on the air flow meter or painted parts.
