Better engine performance.Fit Type Universal. Lower fuel consumption. Lower pollutant emissions. Protection against corrosion and carburetor icing.

Carbon Deposition- There are some hydrocarbon olefin residues attach on engine intake, cylinder when fuel burn in engine not completely. These residues change into hard black shell in high temperature condition , that called carbon deposition. Carbon deposition will decrease air-fuel ratio, cut down engine output power, increase fuel consumption, engine drastic shake on idle status...all the thing will hurt engine deeply. So normally we should clean carbon deposition after every 40000-50000 KM.. AUTOOL HTS558- A special machine for engine Intake pipe and intake valve back side clean. Close intake valve, then spray walnut powder into engine intake via air pumpnot include, meanwhile HTS558 will recycle walnut powder by vacuum. This is a closed loop.  Walnut powder will impact carbon deposition on inner wall of intake pipe. After thousands of impact,  carbon deposition will be clear thoroughly.. Chemical cleaning agent will corrodes pipe and shortens the lifetime of engine. Walnut powder is pure natural polish material. It show high performance in  hardness, anti-pressure and wear-resisting. Walnut powder hardness was lower than metal but higher than carbon deposition. Take these advatages, AUTOOL HTS558 will clean clean intake pipe and back side of intake valve thoroughly but no damage.. High-precision engine system is sensitive to foreign matter of intake pipe, such as BMW valvetronic system. That is why we need AUTOOL HTS558 to clean  carbon deposition in intake pipe. Engine should be closed before clean, then turn crankshaft to close intake valve. AUTOOL HTS558 clean one intake pipe each time, 6 cylinder engine should cleaned 6 times one by oneand so on. AUTOOL HTS558 is specail for intake pipe and intake valve back side clean only, if you want to clean carbon deposition on injectorthrottle valvecylinder, please choose AUTOOL CT150,AUTOOL CT200 or AUTOOL C100. Walnut powder not include in package, please get it in local market High pressure air pump is requirementnot include in package Walnut powder residual in intake pipe will go to ashes in high temperature after engine start. Ship from U.S. warehouse.
