Deeply remove highly sticky carbon deposits from your engine’s intake manifold, intake and exhaust valves with the AUTOOL HTS558 walnut-sand system, restoring airflow and idle stability.
- Deep-clean carbon deposits on the intake manifold, intake and exhaust valves to help recover your engine power and ensure a stable idle.
- Walnut sand (walnut powder) is a natural polishing material with hardness between carbon deposits and metal, non-toxic and corrosion-preventive, delivering thorough cleaning without damaging your intake components.
- External air source drives the walnut sand grit for more effective deposit removal, while a built-in dust filter lets you separate grit from deposits for recycling in your process.
- Integrated design enables spray and grit recovery in a single operation, backed by a 3-year warranty for non-human-factor damage.
