Make the handover useful
Keep the removed airbox halves, intake tube and clips together. Record the kit and replacement-filter numbers along with mileage. A future inspection should be able to tell which parts belong to the kit and which are original equipment. If a bracket or hose is missing, resolve the missing part before proceeding; a completed-looking intake with an improvised support is not the documented installation.
