How Often to Change Your Spark Plugs

Spark plugs generally need to be changed at least once every 30,000 miles. If you want to know exactly how often to change your spark plugs, we recommend that you check your owner’s manual or reach out to our service team today. After all, no two vehicles are exactly alike! Read on to learn the signs of dying spark plugs and find out why these small components are so essential.

When Do You Change Spark Plugs? 

For most Rumson and Colts Neck drivers, that 30,000-mile interval will translate to roughly two or three years on the road. So if it’s been a couple years since your last spark plug replacement, it’s a good idea to schedule service today.

With that said, there are several tell-tale signs of bad or dying spark plugs that discerning drivers will want to watch out for:

• Slow or no start
• Engine misfire
• Engine is running rough
• Rough idling
• Poor acceleration
• High fuel consumption

What Do Spark Plugs Do?

You change your oil on schedule and you always rotate your tires, so why should you worry about your spark plugs? These small but essential components play a very important role:

• Spark plugs create the charge that allows your engine to start, putting your pistons in motion.
• As you drive, your spark plugs ignite the combination of fuel and air that enters each piston’s chamber with every rotation. This spark creates the explosion that is harnessed by your engine in order to move your vehicle forward.

Benefits of Changing Your Spark Plugs

You’ve already seen some of the issues that can develop if you don’t know how often to change your spark plugs, so it shouldn’t be surprising to learn that there are exciting benefits that come with changing spark plugs on schedule. These include:

• Increased Fuel Economy: Worn-out spark plugs can reduce your fuel economy by up to 30%, and replacing your spark plugs can help you save money on every trip.
• Smoother Starts, Smoother Combustion: Engines are high-precision machines, and when your spark plugs work properly, you can reduce the risk of damage or accelerated wear with each combustion cycle.
• Cleaner Emissions: Better gas mileage is one side of the equation, and cleaner emissions is the other! When your spark plugs are working properly, you can burn fuel with less waste.
