Which action is NOT part of Checking the Air Filter?

• A. Remove debris from air filter
• B. Wash filters from inside out
• C. Pull apart and clean all components
• D. Replace spark plug

Answer: (D)

The action being tested here is about proper maintenance of the air filtration path, not the engine’s ignition system. Checking the air filter means making sure the filter is clean and properly seated so the engine can breathe clean air. You’d remove debris from the filter to restore airflow, and you may wash the filter if it’s a type that can be cleaned (often from the inside out to avoid dragging dirt to the clean side) and reassemble once it’s dry and in good condition. Disassembling more than necessary—pulling apart and cleaning all components beyond the filter housing—goes beyond a simple check and can lead to damage. Replacing the spark plug is separate maintenance tied to the ignition system, not the air filtration check, so it isn’t part of this process.
