Toyota Camry Land Cruiser Prado 90919-01289 spark plug FC16HR-Q universal direct install.

When your vehicle experiences idle shaking, weak acceleration, noticeably higher fuel consumption, or cold-start difficulty, it usually indicates that the spark plug electrode is severely worn or carbonized and aged, requiring timely replacement. This spark plug is responsible for igniting the air-fuel mixture during normal engine operation to ensure complete combustion, smooth power output, and fuel efficiency maintenance. This product OEM number is 90919-01289 / FC16HR-Q, compatible with Toyota Camry (2000-2010), Land Cruiser (2000-2010), Previa (2000-2010) and other models. When installing, be sure to use a torque wrench to tighten to the specified torque, and check whether the ignition coil boot is aging to avoid leakage or high-voltage breakdown due to poor sealing.
