How to Replace Car Spark Plugs

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

Replacing the spark plugs is something you can do yourself if you have good manual skills. Worn spark plugs can lead to problems such as exhaust smoke, difficulty starting, and increased fuel consumption. To proceed with the replacement, you need a socket wrench. Remove the cap from the first spark plug, use the wrench to unscrew the old spark plug, and screw in the new one, connecting it to the lead. To prevent mixing up the order of the ignition leads, it is advisable to complete the replacement of the first spark plug, then disconnect the second lead, and so on with the third and fourth.
