AUTOOL HTS518 Carbon Cleaning Machine is able to deeply remove the adherent carbon on the intake manifold, intake valves and exhaust valves, and effectively improve the problems of unstable idling, insufficient air intake, insufficient power and insufficient acceleration of the car.
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.
