Removal And Installation Of Engine Intake Parts

If any metal tip is mixed in the inlet pass, that may give a bad effect to the engine and turbocharger.
When removing and installing the inlet system parts, close the opening of the removed inlet system parts and the engine with a clean waste cloth or gummed tape. See Fig 1.
