Does Volkswagen use Bosch or NGK spark plugs?

[OAdalynn]

Bosch brand spark plugs are used because Bosch is a German company, making it more compatible with German vehicles. Bosch offers a variety of products, and spark plugs are just one of them, but this does not mean their quality is inferior to other brands. Function of spark plugs: The main function of spark plugs is to introduce the high-voltage electricity generated by the ignition coil into the engine cylinder under the control of the engine computer, creating a spark between the electrodes to ignite the air-fuel mixture, thereby ensuring normal engine operation. Since diesel has a lower ignition point and can be ignited by compression alone, diesel engines do not have spark plugs; only gasoline engines use them. Considerations when choosing spark plugs: It is important to know the diameter of the spark plugs used in the vehicle, as well as the heat range of the engine's spark plugs. Additionally, the material of the spark plugs should be considered. It is best to replace them with platinum spark plugs, as they have a longer lifespan and provide faster ignition response, serving the engine more effectively.
