A. Cleaning the turbo (inlet side) without disassembly.

• Start the engine and let it warm up.
• Remove the flexible hose in the intake system, located between the air filter box and turbocharger / intercooler.
•  For petrol engines run the engine up to 2000 rpm.
• For diesel engines let the engine idle, NEVER throttle.

• Spray Wynn’s Turbo Cleaner in short intervals to avoid a spontaneous increase of rpm and engine knock.
• After each spraying wait for the rpm to set back to the original level.

• Let the engine run at least another minute before stopping.
