You can instantly restore your engine’s air-fuel balance by targeting stubborn carbon crust behind intake valves with the AUTOOL HTS558 walnut blaster.
You control the blast pressure directly through the handheld trigger while your external vacuum line captures every particle of spent abrasive and dislodged soot.
You supply an air compressor rated above 0.7MPa and load 2–4 kilograms of 0.4–0.8 mm walnut grit to safely shatter thick hydrocarbon scales without scratching your cylinder heads or valvetronic components.
You separate reclaimed media from pure carbon waste inside the dedicated dust filter, which lets you reload and reuse the same abrasive across multiple vehicles.
You power the unit through any 110/120V outlet and mount the included spray wands, eye shields, and quick-connect return hose on your current workstation.
