(cleansing foam) is a mix of substances specifically designed and developed to dissolve all dirt residues present inside the combustion chamber. Eliminates encrustations on the cylinder head, especially those present on the valves and on the first piston ring. The valve seats (if they are open) are also cleaned. Even residues present on the EGR valve, the turbo and the intake system (pipe and inlet valves) are effectively eliminated. i It does not attack gaskets and is compatible with all aggregates present in the engine. The K2 component (neutralizer) generates a chemical reaction with component 1, diluting the cleaning foam and chemically binding the dirt residues that dissolve. The Carbon X Extractor (34142) is then used to safely eliminate the emulsion and carbon residues fro.
