Spark plugs serve as an integral part of a car’s ignition system, providing the needed spark to ignite the air/fuel mixture in the engine cylinders. Over time, however, spark plugs become worn, corroded, or even fouled resulting in poor engine performance, increased fuel consumption, and even total engine failure if ignored.
What is the Average Cost of Replacing Spark Plugs?
The cost of replacing spark plugs varies depending on a variety of factors such as the car make and model, the number of cylinders, and the type of spark plugs used. On average, however, the cost of replacing spark plugs falls between $100 and $800.
