What is the model number of the Vios spark plug?
1 Answers
Toyota Vios uses Denso spark plugs from Japan, with the model number C16HR-U11 and a heat range of 5, which are high-end products from Denso. Here are the specific details about spark plugs: 1. Spark plugs, commonly known as sparkers, function to discharge the high-voltage pulses sent through the high-tension leads, breaking down the air between the spark plug electrodes to generate an electric spark that ignites the air-fuel mixture in the cylinder. 2. The main types of spark plugs include: standard spark plugs, extended insulator spark plugs, electrode spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs. 3. The purpose of a spark plug is to introduce tens of thousands of volts of high voltage into the combustion chamber and generate an electric spark to ignite the air-fuel mixture. Working in conjunction with the ignition system and fuel supply system, it significantly determines the engine's performance.
