Changing the spark plugs on your Mazda 3 is very easy. Gather: 4 new spark plugs, a 16mm socket for removing them, and two additional sockets of 8mm and 15mm. Perfect, open the bonnet and separate the cover from its housing.

Using the 15mm socket, unscrew the two bolts of the cover and place them in a safe location, remembering their position; alternatively, you can replace one spark plug at a time. Now, take the 8mm nut, carefully unscrew it to avoid dropping it into the engine bay, and keep it safe.

Disconnect the connector from the ignition coils by pressing the tab and pulling it towards you. Now you can remove the ignition coil, then using the appropriate socket, unscrew the spark plug and replace it with the new one after comparing it with the old one to ensure they are the same.

Refit the ignition coil and connector in their place, screw in the 8mm nut, then the cover, and finally, secure the plastic back in place.
