| AUTOOL HTS558 is a carbon deposition device for intake valve cleaning, whose working principle is to blast the walnut media into the intake valve through high-pressure airflow. The carbon deposits on the valve and cylinder wall impacted down. The walnut media and carbon deposit mixture can be recycled through special joints. It can deeply remove the sticky carbon deposits on the intake manifold, intake valve and exhaust valve. Effectively solve the problems of unstable idling, insufficient air intake, insufficient power, and insufficient acceleration. |

| External Air Source This enables the walnut sand grit to strike the carbon deposits more powerfully and efficiently. | Integrated Design The walnut sand grit can be sprayed & recovered simultaneously. | What is walnut sand Walnut sand is a pure natural polish material, its hardness was lower than metal but higher than carbon deposition, it will clean intake pipe and back side of intake valve thoroughly but no damage. |
 | How to use: Open head cover of HTS558 and pour into walnut powder (need 2- 4KG ), press dust guard on walnut powder then close cover. Join spary gun muzzle and recycle hose together (there is a hole on recycle hose). Remove intake manifold of engine, plug spray gun into intake, turn crankshaft to close intake valve. Connect high pressure air pump (not include) to HTS558. Connect AC power, start clean. The process should last 1-3 minutes (depending on carbon deposition circumstances).Close HTS558, check up cleaning result. Normally, walnut powder can be reuse 5-10 times (depending on carbon deposition. circumstances) |
