It cleans intake ports and valves, and the combustion chamber through the spark-plug hole where the vehicle service procedure supports it. An external compressor is required and not included.<\/p>\n<ul class=\"abd-facts\">\n<li>Blast + Recover Together<\/li>\n<li>HEPA Filtration<\/li>\n<li>Recovery \/ Filling

class=\"abd-features\">\n<li>\n<h5>Integrated Recovery and Filtration<\/h5>\n<p>The machine sprays and recovers at the same time; a filter cartridge and screen separate carbon from walnut media so suitable media can be reused.<\/p>\n<\/li>\n<li>\n<h5>Recovery and Filling Modes<\/h5>\n<p>Dedicated switches for recovery and media filling, with power and filling indicator lights on the control panel.<\/p>\n<\/li>\n<li>\n<h5>Dual-Mode Nozzle Handle<\/h5>\n<p>Switch between blasting mode for carbon removal and air-only mode for clearing residual media and deposits.<\/p>\n<\/li>\n<li>\n<h5>Pressure Control<\/h5>\n<p>A pressure gauge and regulating knob let you monitor and set blasting pressure per the manual.<\/p>\n<\/li>\n<li>\n<h5>Intake, Valve and Combustion-Chamber Cleaning<\/h5>\n<p>Work port by port across intake manifolds and intake valves; combustion-chamber, exhaust-valve or other extended-area cleaning only where the vehicle procedure supports it.<\/p>\n<\/li>\n<li>\n<h5>Workshop Mobility<\/h5>\n<p>Handle and 360\u00b0 swivel casters move the unit between bays.<\/p>\n<\/li>\n<\/ol>\n<\/section>\n<section class=\"abd-sec abd-hls\"

class=\"abd-tag\">Caution<\/span><\/h5>\n<ul>\n<li>Requires an external compressor supplying dry, filtered air; check that the tank, hose, fittings and duty cycle support the required airflow.<\/li>\n<li>Never blast with the target valve open, and do not clean an area just because the nozzle can reach it.<\/li>\n<li>The adapters and nozzles fit multiple port shapes but are not universal; confirm fit and seal on each engine.<\/li>\n<li>Remove all visible residual media before starting the engine rather than relying on it to burn away.<\/li>\n<li>Walnut-shell dust may trigger allergies; wear goggles and respiratory protection, ventilate the area and follow the media supplier&#8217;s SDS.<\/li>\n<\/ul>\n<\/div>\n<div class=\"abd-note-group is-care\">\n<h5><span
