The Bosch Ignition Coil Kit - 140691 is a comprehensive kit of products designed to service the ignition system of a car. It includes three essential components: an ignition coil, a spark plug, and a wire set. These components work together to create the electrical spark that ignites the fuel in the engine, allowing the car to start and run smoothly.

The ignition coil is responsible for converting the low voltage from the battery into the high voltage needed to create a spark. The spark plug then uses this high voltage to ignite the fuel in the engine. The wire set connects the ignition coil to the spark plug, ensuring a steady flow of electricity.

This kit is designed to provide a reliable and efficient ignition system for the car, ensuring optimal performance and fuel efficiency. It is suitable for a wide range of car models and makes, making it a versatile and convenient choice for car owners.
