How to Replace the Spark Plugs on a Mazda 6

Model: Mazda 6 MK 1, GG - Years 2002-2008
Part: Spark plugs

To change the spark plugs on your Mazda 6, disconnect the coil connectors as shown in the video. Twist to remove all coils from the car. Once extracted, use a socket wrench to unscrew the spark plugs as demonstrated. Compare the worn plugs with the new ones to ensure a proper match. Use a coin or metal piece to widen the spark plug tab. After modifying all plugs, reinstall them into the engine head, remembering to screw them in gently to avoid damaging the threads. Refit the coils and the connectors.
