Diesel Intake System Cleaner The Diesel Intake System Cleaner removes typical contamination and deposits in the entire air intake, combustion and exhaust system: eliminating soot residues and carbon deposits on the working surface of the Diesel Particle Filter (DPF), combustion chamber, cleans carbon deposits in the ERG valve and turbo charger. Dissolves gum, lacquer, tar, carbon and deposits Restores perfect airflow towards the combustion chamber Engine runs in a regular and stable manner while idle Restores or maintains the engine performance and fuel consumption Eliminates and avoids starting problems Reduces black exhaust emissions Positively influences the functioning of the lambda probes and the catalytic converter
