How often should you replace your car's spark plugs?

It is generally recommended to replace spark plugs every 30,000 to 100,000 miles, depending on the type of spark plugs installed in your vehicle. However, it is important to consult your car's owner manual or the manufacturer's recommendation for the specific spark plugs used in your vehicle, as some newer models have longer-lasting spark plugs that may not require replacement as frequently. Additionally, factors such as driving conditions, fuel quality, and engine performance may influence the replacement interval of spark plugs.
