AUTOOL HTS518 Walnut Sand De-Carbon Cleaner adopts the physical Harmless Technology of walnut sand cleaning and is specialized in efficient and non-destructive cleaning of engine carbon deposition. The walnut sand is injected into the intake manifold of the engine through the high-pressure airflow.
Works well and seems to be of reasonable quality. The machine is not stable when you put anything of weight in the back pocket. None of the grommets supplied seemed to fit our car very well. We ended up putting a bend in the firing pipe. The scraping and vacuuming out did the most work, with the machine unable to cope with larger deposits.
