The Benefits and Costs of Changing Your Spark Plugs
Changing your spark plugs can provide several benefits for your vehicle. It can improve fuel economy by ensuring the engine is running efficiently, reduce emissions, and increase engine performance. Additionally, replacing spark plugs regularly can help to prevent engine misfires and other issues that can cause costly repairs.
The cost of changing spark plugs varies depending on the type of vehicle and the type of spark plugs being used. Generally, spark plugs range from around $5 to $20 per plug. Additionally, you may need to purchase additional tools if you don’t already have them. Labor costs can also vary depending on the complexity of the job and the mechanic performing it.
What You Need to Know Before Changing Your Spark Plugs
