Important Notes from AUTODOC Experts

• The replacement process is identical for all spark plugs.
• When tightening the spark plugs, do not use excessive force, as this can damage the threads.
• Be careful when working with a spark plug socket, as improper angle can lead to damage to the thread connection.
• Ensure the engine cover is properly seated and not shifted relative to the mounting elements and throttle body air intake.
• Do not use excessive force when installing parts, as this may damage the fasteners.

Congratulations!
