What is the torque specification for the Mazda3 spark plugs?
1 Answers
The installation torque for Mazda3 spark plugs is between 15-20 Newton meters. Main types of spark plugs include: standard spark plugs, projected insulator spark plugs, electrode spark plugs, seat spark plugs, pole spark plugs, and surface gap spark plugs. Spark plug replacement intervals: Under normal maintenance conditions, replacement is recommended at 40,000-60,000 kilometers. However, this may vary depending on the brand and engine type. Always refer to your owner's manual for specific recommendations. Maintenance replacement reference standards: Platinum spark plugs at 40,000 km, conventional nickel alloy spark plugs at 20,000 km, and iridium spark plugs at 60,000-80,000 km. How spark plugs work: Under high voltage, the air between the spark plug's center electrode and side electrode rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between electrodes reaches a certain level, the number of ions and electrons increases avalanche-like, causing the air to lose insulation properties and forming a discharge channel - this is called "breakdown." At this moment, the gas forms a luminous body known as a "spark." Accompanied by thermal expansion, it also produces a "snapping" sound. This electrical spark can reach temperatures of 2000-3000°C, sufficient to ignite the air-fuel mixture in the combustion chamber.
