The Delphi Ignition Service Kit - 473985 is a comprehensive kit designed to service the ignition system of a car. It includes a variety of products to ensure the proper functioning of the ignition system, which is responsible for starting the engine and powering various electrical components in the car.

The kit contains two main components - an ignition coil and spark plugs. The ignition coil is responsible for converting the battery's low voltage into the high voltage needed to create a spark in the spark plugs. The spark plugs, on the other hand, are responsible for igniting the air and fuel mixture in the engine's cylinders, which is essential for the engine to start and run smoothly.

In addition to these main components, the Delphi Ignition Service Kit also includes various smaller parts such as ignition wires, distributor cap, and rotor. These parts work together to ensure a strong and consistent spark is created, allowing the engine to run efficiently.

This kit is suitable for a wide range of car models and is an essential tool for maintaining the overall health and performance of a car's ignition system. It is a cost-effective solution for car owners who want to ensure their ignition system is in top condition, without having to purchase individual parts separately.
