When to replace spark plugs on Mazda Demio?
Inspect each spark plug for each cylinder separately. The electrodes should look light brown as shown in the picture to the right. Check the gap between electrodes. It should be between 1 to 1.1 mm. If your spark plugs have more than 45,000 km, replace them. Tighten to 2.5 mKg (18 ft-lb) when refitting. A website, I did myself…
How does the gap on a spark plug work?
A spark plug has a relatively simple construction and is nearly maintenance-free, except for the adjustment (gap) of its electrode and periodic cleaning or replacement. Setting the gap on the spark plug electrode determines the voltage length and duration of the spark. A spark plug that has an improper gap will show certain signs and symptoms.
What causes a high voltage spark to jump the gap?
A high voltage spark jumps the gap, producing ignition fire. Spark plug specifications, which include type, heat range and gap, will be found in the owner’s repair manual. Heat range indicates the length of time needed for heat to be drawn away from the plug tip.
What are the symptoms of a narrow spark plug?
The symptoms of narrow gap include a noticeable (continuous) cylinder miss, hard starting if all the plugs have narrow gaps, rough idle and engine hesitation. A spark plug that does not fire, resulting from a narrow gap, will appear black or wet when inspected. The black or wet appearance indicates unburned fuel.

Do you need to set the gap when installing new spark plugs?
DO I NEED TO SET THE “GAP” WHEN INSTALLING A NEW SET OF PLUGS? Maybe. A spark plug part number might fit hundreds of different engines from many different manufacturers. Although the NGK factory will set the gap to a preselected setting, this may not be the right gap for your particular engine.
How big is the spark plug socket on a Mazda 3?
The 14mm socket was also an Amazon item as well. Stores only seem to stock the standard 16mm and 18mm plug sockets. Our cars use coil on plug so there’s no wires to replace.when you end up doing this job, I recommend applying a light coating of anti-seize lubricant to the plug threads and dielectric grease to the coil end of the plugs.
Where is the spark plug gap on a champion?
For Champion spark plugs it is a little less logical and is as listed below: Spark plug gap is where spark plug spark discharge is designed to take place. On a conventional spark plug, it is the area between the center and the ground electrode.
