What is the original spark plug model for the Corolla Hybrid?

[AliyahFitz]

Corolla Hybrid's original spark plug model is Denso SC20HR11. What does a spark plug consist of: A spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. What are the types of spark plugs: 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. How does a spark plug 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 the electrodes reaches a certain value, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties and forming a discharge channel, resulting in a "breakdown" phenomenon. At this point, the gas forms a luminous body, known as a "spark." Along with its thermal expansion, a "crackling" sound is also produced. The temperature of this electric spark can reach as high as 2000-3000°C, sufficient to ignite the air-fuel mixture in the cylinder combustion chamber.
