Features & Benefits

  • Does not require complete disassembly of the intake manifold and cylinder head - easy to use
  • Allows removal of scale and soot accumulation from the intake manifold - cleans without dismantling the cylinder head


Cleaning should be carried out in strict accordance with these instructions:
• Ensure the oil level does not exceed the max.
• Engine temperature (over 80 °C).
• Put a „KENT TURBO FAP CLEANER“ in the fuel tank.
• Pour +/- 1 l KENT Diesel Air Cleaner into steel container, fix cap/ manometer onto the bottle, apply 1.5 - 4 bar.
• Disconnect the EGR valve (helps maintain the venturi effect).
• Put an external exhaust system on the car exhaust or work in a well ventilated environment, this is essential.
• Allow the engine to run slowly.
• Position the large venturi over the mouth of the air intake,to be used for engines of 1.6 l or larger. Use the small venturi for engines of 1.6 l or less (never inject cleaner through the intercooler and/or through the turbocharger).
• Regulate the flow of product injected to keep engine knocking under control.
• If a slight knock develops, reduce the engine speed.
• At the end of cleaning, do not immediately remove the venturi, wait 5 to 10 minutes in order to drain the pipe.
• Use „KENT ENGINE FLUSH“ in the oil system.
• Perform an oil change and replace the engine oil filter.
